i think the best advice i can give is look into the RCD 6 inch lift which includes bilstein shocks as replacements...if you dont want RCD maybe you can score some bilstein parts numbers in the process.
Bilstein does make a 6" lift shock, as do they make any size shock you want. I got new bilsteins for my 96 gasser and told them the distance between the mounts and that I wanted 8" of articulation both ways...they made them!
My brother is goiig to be selling his Bilstein 5100 series shocks (stainless ones) off his truck in the next day or so. He's got a 6" lift and they only have 8K miles on them. Think he's going to try the Rancho adjustables as he has a heavy camper. PM me if interested. I think he said he wanted to get $180 out of all 4. 2 have boots 2 don't.
If that doesn't work call RCD. Bilstein makes the 6" longer shocks for their lifts. they will give you a place to order them from. it is what i did for my fabtech lift and i can't find the part numbers right now. 5100 series
oh and i hated my adjustable ranchos. but that was 10years ago sooooo.
