The Stovebolt Site Forums The Parking Lot Panels 'N Burbs 46 panel truck

Hello My name is Calvin from Saskatoon Canada and I am new to this site. Two years ago I purchased a 1946 chev panel truck. Originally the panel was an old delivery truck for a local bakery that just so happens to be in business to this day. I am not going all original on this project. My plan is to rework the fenders and running boards and keep the body as close to original as possible and not disturb the original paint and signage on the main body. I have put a 61/235 truck motor in that had been rebuilt just before it was parked 25 years ago, put in new battery and cleaned the carb and it fired right up (runs like a clock). I plan to use the S10 four speed standard transmission. I have put 1954 chev car front brakes on the 46 front axle, that went on with very little modifications. I am hoping to go with a dual master cylinder assembly, the original single master cylinder mounted to the side of the transmission but I am finding that there is very little room down there with the S10 trans in place. If there is any body out there that has done this before I would be open to any suggestions to help solve to problem. Now I need to figure out how to post a picture of this old gem.

Welcome to the Stovebolt, Calvin. Sounds like you have found a nice panel to work with. Not familiar with the master cyl. question but I'm sure someone else is.....so hang tight, someone will be along shortly.

Will S-10 manual transmission mate up to 1961 235 c.i. engine (w/o modification?)

It should work quite well for you, On the S10 transmission I cut 3/8" off of the end of the input shaft where the pilot bearing rides, shamfer it up so that it does not jam up when you go to do the install. Then I drilled out the 4 metric holes that bolt the transmission to the bell housing to 1/2" you could go to 33/64" if you want a little wiggle room. Then you need to check the length of the sleave where the throw out bearing slides and make sure that length is the same as your 61 trans. if not it is very easy to shorten. I just put a hose clamp around it at the required lenght as a guide and used a zip disc to cut it off, careful not to damage the input shaft then I dressed it up with a file. I used the original flywheel and preasure plate and throw out bearing but had to change the clutch disc to acomidate the S10 spline. My neighbour had a brand new disc from a 92 pontiac sunbird (V6) it fit just right. In your case check the lenght of your drive shaft and also the spline on your yoke to make sure all is happy. Smooth shifting! If you want overdrive you can use the T5 trans out of the S10 but becarefull they have been known to have problems with the 5th gear counter shaft. Also check the end of your speedo cable if it is not the same that can be easly solved but that is for an other email. Good luck

Dan, Sorry I just noticed the W/O part of your question. I digressed a bit, you will need to do some modifications!

My computer skills are limited, can anybody tell me how to attach a picture of my project?

Your driveline questions should be asked in the Driveline forum.

Thank you I will check it out
Calvin:)

On my 46 pickup I have the original bellhousing that has the mount for master cyl (3 hole boss) cast from the factory. Had to grind a bit off the side of my S10 T-5 trans and also the factory master bracket. To mount the later trans to your 46 bell housing you'll need an adaptor to get from the tiny stock trans pattern to the later. If you've tossed the original bell housing you well then need to fab something else.
Best of luck

My 37 is similarly built and I have a S10 t-5 behind a 57 235,I also have a dual master cylinder but had to use one from a mid 70s Ford truck since the lines attach to the oppoite side of GM master cylinders.I am using the original pedals and modified it to use with the T-5 and made a bracket to attach the master cylinder to the pedal mount.

I think you are right, It's a good thing I still have the 46 bell housing and it looks like I will need to go with it and the adapter for the S10 trans to make this work. One fellow said to use a master cylinder from a 70's ford truck because they have lines that come out the opposite side. If that's the case I should have enough room down there to make this work. Thank you for you advice on this.

I never thought of going with the 70's ford truck master cylinder, I will have to go and check it out. Will it work with drums all around?
Calvin

The pre 73 Ford trucks have drums all the way around and maybe 73 and 74 4X4s,I think there is a aftermarket Corvette master cylinder that has the brake line ports on either side but I decided on the Ford master cylinder due to availability at any parts store and lower price. I got some 1/8 thick metal and made a bracket to adapt the master cylinder to the 37 pedal mount and I had to cut off where it bolted to the original trans and then made a bracket to go from one of the original master cylinder mounting holes to a bolt on the tailshaft of the T-5 to keep it from flexing

I do have pictures but my computer fried a few months ago and using a borrowed laptop,I am waiting for the after christmas sales to buy a new computer so I can not post any pics.

Hi Fellow Bolters, I got my kids to help me upload some of my pictures.

Hi Guys
First of all I want to thank you people for putting my panel truck up on your galley page I was quite surprised to see it there. I was planning on writing up a bit of the story about this panel truck. It has been a lot of fun and has generated a lot of interest around home here since I have acquired it. Second of all I want thank Jeff and Jim for all their information regarding this brake problem of mine. I tried to find that ford master cylinder up here in Canada but parts suppliers had no success they said it was obsolete?? So I went with the aftermarket corvette one that Jeff had talked about. It did have the ports on both sides so that made it much easier for me. Also I stayed with the 48 bell housing, I just didn't want to back track. So I made my own mounting bracket for that dual master cylinder to incorporated both clutch and brake peddles. It was a big job (lots) of measuring but turned out just fine. It is a bit on the beefy side but I am quite happy with it. I have some pictures if anybody is interested and I did make up some rough drawings but keep in mind this is quite a project in it's self.

Also Thanks to Marvin Ribbich for your advice and drawings.

oid iron46, you can still type up something to go with your panel gallery submission. As Peggy or one of the volunteers get time they will add it to your page.
Pictures, you bet, we love pictures here so we'd be glad to see them. If you can put your "build" pictures on a link, like photobucket, and they'll be around to help folks when we are long gone and most have forgotten how to work on these old trucks. Pictures are great and worth a thousand words. Besides, curious minds want to know anyway..
