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!
