3/4 ton have same crossmember as 1/2 TON? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

wbr775 · 09-29-2009, 03:04 PM

so my neighbor will sell me a 3/4 ton 75 Chevy for $100. I have a 69 4 wheel drive 1/2 ton that i want to convert to 2 wheel drive. my question is can i use the crossmember and a-arms from the 2 wheel drive 3/4 ton truck and change out my crossmember in my 69 to make it 2 wheel drive? is the 3/4 ton crossmember different from a 1/2 crossmember? will it bolt right up? i know the hubs are diffrent since it is 8lug but i planned on using drop spindles so no problem there. any help would be greatly appreciated thanks Ian

My buddy Justin, Quadracer812, is doing that swap to a 65-66 right now. I believe he found it to all swap just like the 1/2 ton will. You might look for his posts in the 60-66 section and find some more info.

The cross member itself is the same, but the control arms, ball joints and shafts are different. Steering parts should be the same.
