i have a guy that will give me a set of 4' lift springs outta a 79 now looking they looks similar to my stock 91's but most coils look alike will these fit without problems?

compenstate for some sag say i get 3 inchs outta it w/ a 3 inch block in the back whats the biggest rubber i can put on it? he has a set of 36's for sale too

how high can i go before i pitch a drive shaft cuz its too short now??

thanks FTE

 

annnnnnnny one?

 

man, your crunching alot of "what if/ maybe" numbers... and considering the price for a nice set of big mud tires, i'd personnely make sure it all fits on first - then go tire shopping... plus you got to remember the other little things like steering linkages, brake lines and such. sounds like a good swap- just make sure you got a plan B before you go doing the mods. best of luck to ya
