92 xj 32 tooth speedo gears (part number)

I need a 32 tooth speedo gear for my 92 xj on 31's but i cant seem to find the part number. I checked a few links but none of them list a part number for a 92??

Anyone

"Accuratizing" my '92 XJ's speedo is on my list, as well.
Info I have shows no 32 tooth gear. Looking at my IPB (Illustrated Parts Breakdown, Figure 21M-2600), '91 - '93 speedo gears appear to run from 29, 30, 33, 34, 35, 36, etc....
Good luck.

ps My first post. Great forum, gents.

someone must have done this?

I think a 32 tooth for a 93 wasnt made. Just use the 31.
