i didnt know, ot fogot about that 5th gear being different in LT77s.Something I'm just discovering now: pre 200tdi LT77s have a lower gear ratio in 5th than the ones that came with 200tdi's (.8413 vs .77). By my math I'm going to be down about 5mph at around 3k rpm. So if people are reporting 65-70mph with the later LT77's at 2800-3000 rpm, I'll be doing 60-65 (roughly) at the same rpm. That's roughly where I think I am now, though I'll find out tomorrow on a highway drive. Maybe it's time to install the 56A LT77 that's just sitting on my garage floor waiting to be cleaned and sealed. Or a stumpy R380.
