yes, 6t + 18t is what you want.

i'm using that w/ my 4.10's and just did the math....i'm overreading about 4-5 mph right now.

3.73's should be right on.

but i'm not so sure the tailshaft pops right off like stated b4.....the shift lever needs to be removed if i remember right.
maybe i'm stoned, i can look tomorrow, my old t5 is torn apart and in my garage, i was taking it apart anyways, not just changing speedo drive gear , so i could very well be way off.

but if thats the case , to get the shift lever detached it is a total disassembly

ORIGINAL: gspfunk

I have the 8-tooth green drive gear and went w/ a 23 tooth white speedo gear ($12 Ebay). Just installed it, but my car is not running yet, so I'll let you know how it works. I have 3.55's, BTW. 3.73's are supposed to use the same gear.
+1 S'what I have and it's perfect for 3.55s. someone told me they didnt make a perfect speedo correction gear for 3.73s in our cars (maybe only 8 tooth) but they def. said white 23 tooth for 3.55, 3.73 and 4.10s...

but according to the chart, a 6t and 18t is good for my 3.73's, right? will that give me the best combo?

did you ever figure out if the shift lever needs to be removed?
