Rear end swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

copywritten · 09-13-2015, 10:33 PM

I bought a posi rear end from a member on here. Came out of a 72 c10 and was going to put it in my 67 but sold my truck. I now have an 86 swb and was wondering if my 72 posi will bolt up in place of my swb 86 rear end?

72 c10's are coil spring rears with trailing arms?

86 rears are leaf spring rears?

if so it wont "bolt in".

the gears and posi might work if they are both 12 bolts AND both the same series, 3 or 4.
