yeah, yeah, I know. Rear brake conversion again!
 

I tried searching previous posts without luck...

I just saw everything to convert a fox to rear discs using sn95 parts for $495. This is rotors, calipers, mounting plate, etc. and includes the 5 lug axles.

I don't want to use the 5lug axles, Can't I use these brake parts and keep my 4lugs?

I converted to rear disc using 86 Thunderbird Turbo Coupe axles, rotors, etc.... the axles for this conversion are 4 lug and are about 3/4 of an inch longer than stock. So I dont think you can use stock axles with that setup you are looking at. Hope that helps.
