I have searched the forums and I cant find a answer to this question. I know that my 90 TB is leaking at the shaft seals, I was going to replace the seals myself but after doing some searching I foud out that there are 2 diferent size shaft seals in the 90 TB. If anyone knows the size of the smaller seal and where to get it that would be great, but if not I'm thinking of swapping over a 91-94 TB. But I have a few questions 1st.

It looks like the ISC, and TPC will plug in without any modification to the wiring. The TPS however looks completely different on the 91-94 then on my 90. My question is can I splice the 91-94 TPS into my 90 wiring harness or are they too different?

Thanks.

Nevermind just did some more digging and found that the bigger o-ring is 7mm and the smaller o-ring is 6mm. Im going to give chicago rawhide and call and see what they got
