if what i'm reading is correct(that you want to sub the front end and the post about the radiator) i've got a couple of points to make.

1st is the radiator.
if you're gonna sub it, wait to buy the radiator as the stock one might not fit (depends on what the ride height is)

2nd is the subframe itself.
78 was a 1 year only on rotors and spindles,it'll only be a problem if you want to go to dropped spindles later (78 rotors won't fit 79-up and that's the only option on spindles)

just thought i'd make you aware of potential problems...

i miss obscene phone calls...
