Hey Y'all!
I'm pretty well versed in the automoblile rear wheel drive world as far as figuring out what driven gear I need and where to find it.
But, I need to know if the gear in my 203 transfer case is the same as a standard T400 driven gear?
1978 GMC K25 454/T400 203 3.73 gears
So, assuming I have the 15 tooth drive gear (that would be in a T400 output shaft) I'd need a 34 tooth driven gear because I have 33's on now.
Is this correct?.....or is there a different style of gears in the transfer case???????
I already ordered the 34 tooth T400 gear...........so I'm hoping I assumed correctly!.,...lol!
Thanks ahead of time!
