as for the top end is there a significant difference in the gear ratios? i seem to recall reading the H55 is .85% (?) but don't know about the 4 spd. is the H55 significantly better?

Hi Steve, I've been looking for my transfer case information; not near the truck now. 1988 LC HJ61 12ht, H55; can you link me to where I can read the info on transfer cases, transmission ratios... the truck is a Sahara model also; just bought it last week.according to the TLCFAQ:
http://www.birfield.com/modules.php?name=TLCFAQ&p=/~ramullen/FAQ/TEXT/08-01.html
H41 transmissions came with three different ratio's (any of these features should discerne what's inside) depending on:
model year ( FJ55: 1969-1971, or pre 1981 with a: B,F,2F,H,2H, or post 1981 with a: B,F,2H)
spline count (of transfercase input): 10, 16, or 19
low-range ratio of: 2.313, 1.992, 1.959
it also illustrated the ratio differences between the H41, H42, and H55-F
Cheers,
Steve
I think you can get an FJ40 top plate so you do not have to relocate the tranny cover. Also, since the H55 is longer, you may have to rework both driveshafts. Go to my build thread, Second 40, and scroll down a bit to see how I moved the hole.
