new to me 64 3/4 ton

[LuckyLightning]

66Submarine and hotrod66, I'm really digging your tires. What size are each of you running?

I got myself some 265/76/R16 tires on some Metal Moto wheels, but they are just a smidge too wide. Was thinking it's the wheels, but they don't seem wider than 16x8. Maybe it's the size of the tires themselves that are making them so wide? I would have expected 265/75 to fit though. I'm afraid if I put anything heavy in the bed, the rear tires will rub on the fenders.

They look like street tires, but they are AT tires. I go back and forth between liking them or not. I'm probably going to sell them in the next few weeks and go back to the "original" steelies with some 235/85/R16 tires (to go back to the look you guys have).

[66Submarine]

Yeah, the stepside trucks don't have a ton of room for wide tires. I have 16x6.5 GM steel wheels with 245/75R16 on the front and 235/85R16 on the back.

[hotrod66]

mine are kinda tight on my old truck dont know if they rub or not yet. i haven't really driven the truck much because one of my motor-mounts is missing still need to find another stool for this truck. back to the tire size there Lt265/75r16 so we are in the same boat

[66Submarine]

It's dark, but I tried to take a couple pictures for you. As you can see, even with 235/85's there isn't an excessive amount of room (IMO). I'm still thinking of trying to wedge a 265/75 in there, but it will be tight...

FWIW, on my truck the 235/85's on the front also rubbed the steering box slightly with the wheels at full right lock (IIRC).

And I just got done with wheels and tires on my "new" car today! Funny coincidence.

[LuckyLightning]

Thanks guys. 66Sub, your rear tires look reeeaaaal close to the fenders, but I take it they are not rubbing when you load up the bed?

[JWheeler331]

I like it.

Hasn't been a problem. That's also the worst side (rear end isn't quite centered) and a truck that hasn't side-swiped a bunch of stuff has a little more clearance IIRC (I'll measure). I pried them back out somewhat the other day, but I'm not sure how close to the original width they are. I think you should be good with 235/85's.

I'm actually thinking of taking a hammer to the fenders again and trying to fit a 265/75 under there.

[66Submarine]

Worse than I remembered; even after prying it out that fender is still around 12.25" wide and my '64 that hasn't been run into as much stuff is about 12.875" (side-to-side alignment of the rear is actually pretty good). Here's a picture of the good side; pretty nice fit with 235/85's IMO.

[hotrod66]

remember lucky our trucks are coil over submarine's truck is a one ton with leafs. our trucks will have more side to side play than his due to the pan-hard bar shoving the axle over to one side, when there is a load it makes it worse.

[hotrod66]

found a matching bed side today. well kinda its off a 66 so i now have 1 reverse light, all-well its better than having one black bed side. i only gave $40 for it so im happy

[Mathew21]

Nice score on the bed side. That would more like $400.00 around my rusty part of the country.

thats a little scary, but there all rusty at this point its just to what extent. every truck i have owned has needed rockers and some form of floor repair. i am sure there are some survivors but there getting harder and harder to find.

[hotrod66]

Well another successful day at the junkyard. I bought the suspension out of a 71
c-20 to put under my 64 so I have disk brakes . I had a hard time trying to get it out with hand tools so the guy that owns the place let me take the hole truck home, have to bring what's leftover back. I also found some neat gmc hub caps and emblem off a old bread truck.

[Captainfab]

Did the '71 have a Dana 60 or the Eaton HO52 differential?

[hotrod66]

Looks like a Eaton like what is under the 64 wish it was a dana

[hotrod66]

Well got the 71 pulled apart I'm certain it's a Eaton differential.
I also painted one of my hubcaps to make it match the truck.
If anyone knows what the axial is for certain please let me know.

[Captainfab]

Yep, that is an Eaton HO52/72. You might be lucky and it will have 4.10 gears.

Hopefully it is I was told the trucks that were automatic had 4.10, whether that's true or not I don't know.the truck the axial came from was a 4 speed.

Unfortunately, that's not true.
