The Stovebolt Site Forums The Parking Lot Big Bolts 1968 GMC 6500 2 Ton Truck

Hello everyone. I am new to this site and I have come here seeking help in my project truck. I am from North Carolina and I am 19 years old. About 7 years ago my grandfather gave me this truck and I have been restoring and fixing it up since while putting my own twist on it. If anyone has any cool facts or information about this truck please let me know. I am also in need of suggestions or possible locations of a parts truck. Thank you :D

Go to this link, then scroll down to the bottom and click on Vehicle Information Kit. Eventually you select the year of your truck.

On this sites homepage there are links to parts vendors.

Thank you for that. And to correct myself this is a 4500 truck.

I'm having a hard time finding a master cylinder for this truck that isn't 400$ the original one is too pitted to repair. Anyone have somewhere for me to find one cheaper?

Welcome to the site.

Post a link to some pictures, if you have a reasonable way of producing some.

Get it sleeved at a machine shop. Good luck. Jim

Actually, it's on the top of this page, too. Just scroll up

Welcome to the Stovebolt

As others have said, don't scrap your old MC, there are companies the specilize in sleeving them so they can be rebuilt. Apple Hydraulic is one company that comes to mind,

Can I post pictures directly on here

Isaiah, check with White Post Restorations in White Post Va. They used to bore and put SS liners in brake cylinders

No. Refer to the photo policy on the left side of the page.

Isaiah;

The photo album comes up as Private. You will have to share the folder.

SimS

Yep,NO ACCESS!

http://s447.photobucket.com/user/iwashington1664/library/Mobile%20Uploads. These should work now

Nice looking truck. You are doing a good job on fixing it up.

SimS

Truck is looking good.

I see that it originally had a 305 V-6.

Bill

how do I view these pics without the big checkmark in 'em?

You COULD upgrade to a dual reservoir master cylinder;either get one with the same bore size for a drum brake truck or use one with the same bore size for a truck with front disc brakes and use an aftermarket adjustable proportioning valve in the front brake circuit. On my '54 GMC 2 ton I used a M/C for a GM one ton van-same sized bore,works so well it feels like power brakes,and I can load more or less front brake with the twist of a knob.

Could you possibly send a link to the mc you used. And also it is random but does anyone have suggestions for where I could get a rubber mat to make a new floor mat out of

I just got a '54 GMC 630 and a replacing the wheel cylinders with new, thought of going hydroboost to replace the hydrovac, so, I am interested in your master replacement.

Did you replace or eliminate the hydroboost? Is that what it came with?

Thanks,

Ed

http://fayetteville.craigslist.org/cto/5128256005.html would any of these parts off of this truck work on my truck ? Thank you in advance for the replies gentlemen

Exterior Cab parts, hardly any.

Interior Cab parts, very few.

Mechanically, most should work.

Pretty good deal there though.

I was afraid of that. I was wanting the windows to worm becuase I am very much in need of a windshield and side window. It's a good deal but the truck is about 5 hours away from me so hauling it would be an issue

Hello gentlemen. Could someone please send me some links or part numbers for the front shocks on my truck. Also for the bearings and kingpins

hello I am in search of tie rods king pins and bearings for my 68, if anyone knows where to get these it is greatly appreciated

Hy Isaiah, could you give us a rough measurement of the length of the kingpin, there are a couple of different options. For the tie rod ends there are at least two different possibilities, what size is the tie rod to cross tube thread?

from what I can tell the kingpin is roughly around 7 inches does that sound right?

Hy Isaiah, it looks like your truck has a 5000lb front axle, it should take Moog p/n 8492B $25.79 at RockAuto. That kingpin is 6.343" long, the 7000lb front axle kingpin is 7.890" so that is too long, hope that helps.

Here's an update on my progress tell me what y'all think! http://s447.photobucket.com/user/iw...051_zpspbizj9lw.jpg.html?sort=3&o=29

Looking good.

Does anyone have a good place to get a 12 inch clutch kit from for my truc k?

Rockauto or NAPA will have what you need. I find that Rockauto does a pretty good job with pictures and specs, i.e. spline counts, diameters, etc.

SimS

Okay thank you I will check rock auto they seem to be better prices for the budget guys like me

I have the 2 speed axle and the high low control is cable operated I guess you would say , it's not electric. It is extremely stiff. I went down to the box the cable goes to and oiled it it did not seem to help. Any other suggestions to loosen this up because I can't even shift driving it's so stiff. Also could I possibly lengthen this control because I have a shifter extension amd I'd like it to run up the shifter more. Thank you I'm advance for any advice

Isaiah, did you lube the cable itself? on mine, I sprayed the outer cable to lube it and it helped a lot.

I did awhile ago but have not recently, I'll go try that now thank you

if it is like my 55 and 58, that cable is only a couple feet long and most is inside the cab. Mine were just super dirty from years of dust from driving around in the fields.

I hear that, that's all my truck has done for the last 20 years
