There's plenty of reasonable suspensions available for a 1st gen, some realistic some not.
An 8-10 " lift not so much, because it's a little past reasonable. And what's appropriate for your use can be different.
All Pro Offroad, Marlin Crawler, and Trail-Gear (and others) all have suspnesions for 1st + 2nd gen trucks, most in thr 4-8" range.
The better ones will have complete springs instead of adding a leaf of blocks.
