I'll post a few of those threads up later, then add as stuff comes along.

Desert Fox,
IMO the preload vs topout spacer discussion is a thing of the past. most lifts now are 2" or under are topout. Those over use a combination. In the past, there were smaller spacers offered in a preload, buy I don't see that much anymore. If you think it'll be beneficial, I'll add that in. as for lift amounts with the fj setup, I have another thread with that info. There's a link to it in my original post in this thread. Its titled 4th gen: for all who've done the fj swap.

Let me know if there are any other questions or suggestions.
