Don't mean to meddle, but just thought I'd point out that the threads were different on most of the 89 prop. valves compared to a 91. GM changed the thread pitch on the lines going into the valve right towards the end of 89. I had to figure out which thread pitch I had on my 89 before putting a new valve on it. Turned out to be the earlier style.

 

Perhaps the following will help:

1st design: M1.0 tube nut threads (For 1982 - early 1989 applications)
2nd design: M1.5 tube nut threads (Late 1989+)

Good luck to buyer and seller.
