So you guys bashing Rusty's,
Did you have personal experience with him?
Or just "I heard it on the intarweb he is teh suck"
So far I've dealt with 3 lifts from him, only issue on 2 of them was he said "you shouldn't need a tcase drop, and both times we did. He shipped it next day when we called both times, and covered the shipping on that.
As for RE, everyone also says their the awesome. I've dealt with them 4 times. Only once did I get the right, fully assembled part, with all it's bits. (Front upper adjustable control arms)
And every time having to deal with them sending the missing pieces/correct bits is worse than pulling teeth.
So every company/experience can differ.
But for a 93, like was said, i would avoid add a leafs. Your springs are 15 years old. It's time to retire them and replace them with a whole new spring pack.
Edit: If you go the Rusty's route. Call him. Just like DC4wd. Rusty's shipping calculator on his web page is crap. Prices aren't always right either.
