floor pan differance 3 sp. 4 sp... I try search and I get 40 pages of nothing that helps...

I believe those are the same. I've run both trans in my pickup in the past and I don't remember a problem.

What series truck do you have?

They are the same. if anything the hole for the gearshift may be a little larger on the 4 speed but I don;t think so. Besides, you can always cut a hole bigger if needed.

I purchased a floorboard on eBay recently, and I failed to notice that the gearshift opening had been cut larger, about 1" in all directions, eliminating the raise portion. I chose to rework my existing floorboard. I have seen variations of the 46 floorboard with different access holes for master cyl., battery, e-brake handle, but usually for 3/4T up through cab-over. I am not aware of 1/2T difference for 3sp vs. 4sp.

Hi Katrina,
I think the difference is the three speed has a round opening, and the four speed has a square. The master cylinder opening is different on the ½ ton, as it is attached to the brake and clutch pedals, (closer to the center) where ¾ ton and up, the main cylinder is attached to the frame, (closer to the driver door) I have both, and I will take a look tomorrow to be sure. The most unusual would be the ¾ ton with a three speed. I have never seen that floor panel. It is kind of tricky buying one, they all look alike from afar, but they are not.

thanks guys. I seen a bunch of them on ebay and dont want to be stuck getting the wrong one.... and yes I did look at mine on the truck. but it was custom made... holes for a power take-off. and a cut out to remove the battey. and no metal around the hand brake lever and shift. to make it easy to side out.

Also, my friend's '41 half ton has wooden floor boards from the factory, much nicer than the tin stuff.

Documentation???

Documentation-Well I don't have photos, the truck is home in his garage. But I've seen these floor boards and they are much sturdier than the metal ones and would be very easy to fabricate. They had all the holes/cutouts etc. as do the metal. If I were to re-restore my 46 truck I'd go with the wood. I've seen so many metal floors that have been destroyed, folded over drilled full of holes and most not fixable. I did enlarge the battery access area of mine so swapping batteries is no longer an all day project.

I was able to take a look today.
Here is what I found
1941-1946 1/2-ton 3 speed trans:

As for wood, I can attest to the COE as having wood sections left and right, the panel jobs have a wood tool box cover passenger side with a spring-loaded latch. I have only found one of these.

Currently four are on ebay, and appear to be correctly listed for the correct model. Although they are re-pops they look good except they are missing the bump aft of the shifter.

I had asked this question several years back and received many “creative” answers. Do you know what the hole toward the rear in the center is for??

For a finger lift? Inspection hole? Got me?

Mouse door.

I like the mouse door, but when I go to lift the floor panel, it is a natural lifting point. That is the easy part, getting it over the e-brake...grrr....no wonder they are all ripped up.

I was going to fab and form a new floor pan for mine. Bought the metal, cut a 3/4 inch peice of plywood to use as a form complete with all the holes I needed, put it in the truck to make sure everything fit and the holes were in the right location and then it dawned on me, why bother with a metal one. the plywood is very sturdy and probanly insulates against heat and noise better. I used 1/8 aluminum plate for my M/C and battery covers by recessing the edges of the holes with a router 1/8" so they fit flush with the floor. worked out excellent.

Not so much trouble getting it over the gear shift and “E” brake (maybe my holes are a little larger). Mine always hangs up around the brake and clutch pedals.

I haven’t been able to find a boot for my 4 spd. Anyone know who might carry them??

I wondered about this too. I wondered if the plywood would be damaged by the exhaust, should I put a thin sheet metal or aluminum "skin" on the underside, etc? You ARE using this on a 1/2 ton pickup, right? What about the toe board? Haven't taken my boards off yet but there is some kind of funky filler slathered on at the joint between the foot & toe boards, so who knows what condition I'll find once I grind that away to get them out? Have any pictures of your install you can post....PLEASE?!

Pasadena Dan,
I made my floor on my 4t6. You wanted pics. They start here. Have fun and good luck
Dan

Dan,
What year car/truck did the inside rear view mirror come from?

Hi All,
The metal floor boards in the 1940-46 Chevy trucks (all except COE) are NOT the same. The major difference is in the location of the master cylinder inspection cover hole. I have both as I am in the process of reproducing them for resale.....not there yet...but soon.
Brian

The 3spd and 4 spd are different. 4 speed has a square hole and the 3 spd is round. Search e-bay - somone is selling reproductions ones now. No idea how they fit or the quality.

My 3/4 ton came with a floor pan from what looks like a 3/4 ton w/3spd (mines a 4spd). The 3spd was cut out square and the e-brake was moved more to the right. The master hole is on the left and the grooves match that of the 1/2 ton with the 3spd. Did a 3/4 ton even come with a 3spd. in '46?
