there are top shift and forward shift. 89+ are forward. You also have to change out the shift fork by taking the tailshaft off and loosening the 12mm bolt FWIW. I already sold all my shifters, but i still have a shift boot and a top shift 85-88 W55 shift fork that goes on the shift rail inside the tail housing, cheers
This W55 is from an 87 pickup I used to have. I have the shifter. It's going in my 89 that I'm doing a 1UZ swap on. If you come across a forward shifter, let me know. Thanks.
