SBP or BBP?

So the small rear end is such a pile of crap it will blow up with a 318 & a 727?

if its just a driver and your not hooking it up hard a 7 3/4 will probably last a while...

Ok, so what am I looking at to put an 8.75 in it? Is this a bolt up job - or am I looking at grinding every bracket off of something & starting over?

an abody 8 3/4 is a bolt in deal. need to shorten the drive shaft though and make sure you have the proper shock plates. and if you want large bolt pattern your changing the brakes and axles....

a 8 1/4 abody rear is a bolt in. its already bog bolt but you will still have to address the driveshaft. used to be pretty cheap but no so much lately and to me they aren't as good as a 8 3/4.
