Just wanted to say thanks for posting this info Paul...

This was the info I used when I had my new trans built.

I went with 15 drive / 37 driven :cool:

See ? the search function DOES get used once in awhile. :D
 
glad you found it , if you would have posted i probably would have retyped it all over again .

notes
if running gta with 245/50-16s the 39 tooth reads a littlle high , if i were to do again the 41 tooth would have been closer but there was a housing difference to deal with... tci carries them if you need
, there's one specific for 34-39 tooth gears (880042 $27.48 aluminum )
and one for 40-42 tooth gears (880043 $27.48 aluminum),
some times those covers break trying to remove , mine was plastic and broke and you never know till you pull it what gears cover you may have


btw the steel 15 tooth gear is a press on , i heated it up with a torch and used a length of pipe to drive it on .
