Driveshaft question:

I have to agree w/ JohnRR. I appreciate the value of a dollar as much as anyone but, as you said Bill, when one of those wheels goes flying, it's a mess. (And it could happen on the street, who knows who gets hurt then.) Aftermarket axles can be had pretty cheap these days. Myself, I'd save up and get a pair and whatever is needed to go w/ them.
I believe you have 10# of boost and sticky tires? That's gotta be one sleeper 4dr that gets with it!

It's boosted and he is going to run slicks ?

Bill contact dr. diff , he has good axles that'll drop right in for under $400, get the big car brakes off one of those junkyard B body or a C body rear and be done. It'll be cheaper in the long run , you'll twist the splines on the stock axles in short order .

yes you can make a ring for the wheels but if you do that you'll have to blow out the hole in your drum too or you'll never get it off . If you run something like a weld wheel which is lug centric then the center register is not an issue , but twisting the axles will happen eventually ...

pay me now or pay me later ...
