It can be done on the cheap 2 ways;
-One hack the fenders and cobble together some junk yard springs like the front coils off of a ford truck, or the V8 Grand Cherokee coils, and the rear as said before; Chebbies or Dodge Dakotas. Plenty of write ups on here. You'll have a Jeep that rides like crap, but it will handle the 35's... Maybe
-Take your time, check clasifieds here and local boards for used lift kits/parts etc. Take the time to build your parts list up
OR;
Sell or trade the 35's and start smaller, maybe used Budget boost for 31" MT's and some fender cutting. Put a locker in the front, and go out to see how much fun you can have. This takes care of the need it now feeling. Gives you time to scrape together some nice used parts to build your rig.
For a little more cash, you could get some Grand Waggy Dana 44's and some 4:88's and run those 35's by adding to the rear leaf pack, and putting some Wrangler YJ 2" to 4" leaf springs up front... Takes some fabbing skills though...
You could prob trade those 35's for 31's, wheels and tires, and a budget boost with shocks.
Then, after your hooked, you can sell the Mustang and the GSXR and build one heck of an XJ...
