1978 GMC CrossMember in 1960 Chevrolet Apache
 

Hey Guys,

Long question into several short questions ...

I found an (almost complete truck) 1978 GMC C15 front cross member to swap into my 1960 Apache, but i just realized that it's got a 5 lug set up -

1. can I just put 6 lug rotors on from a slightly earlier truck, to get the front rolling?

2. if not, do any of the after market brake kits have rotors that would work for this?

3. does anybody know if I can use a 1978 rear end in my truck?(with the knowledge that I would need to chop off all the mounts and re-fabricate) If I remember right, this might be wider then the stock rear end by 3/4 in on each side? (I'm not running huge tires, so this might be ok?)

I am not opposed to switching to 5 lug all the way around, but I may need to split it into a few stages, as it needs to stay somewhat drive-able and somewhat affordable

It looks like 6 lug rotors are available IF you have HD brakes - 1-1/4” thick rotors..

78 should still be the 1-1/4" rotor, so you should be able to pick up a set of aftermarket 6 lug rotors and use everything else that's still in good condition from the 78. Measure your thickness before you order the new rotors though because if someone had already swapped out the front end with an 80s 1" rotor setup, you won't be able to use the aftermarket 6 lug rotor.

There wasn't a stock 6 lug, 2wd rotor for these trucks. 1/2 ton went 5 lug with the switch to rotors in 71, but the 4x4 stayed 6 lug

I put a square body front end and rear end under my 61. The rear end works but is a little wide. Just cut all the mounting off and order some trailing arm mounts and weld them on.

Thanks everybody!



this sounds good to me - last / follow up question, did you use the stock 5 lug wheels / do you know if they fit?

Re: 1978 GMC CrossMember in 1960 Chevrolet Apache
 

Currently it has stock 15x8 square body rally wheels on it with decent sized truck tires, they clear but are close. I'm actually thinking about using another rear end to get a little wider tire.

The square body rear has no panhard mount but you can overcome this by using an aftermarket adjustable one that's longer and mounts at the spring perch.
