i need to change the gears in my tranny for my speedo to read right when i get my new gears. i've read both of the pages on 73-87.com

http://www.73-87.com/7387garage/drivetrain/speedo.htm
http://www.73-87.com/7387garage/drivetrain/spdgears.htm

but i'm not exactly positive if the part #'s are the same for the 700r4 and the th350 or if the install is the same.

is it the same procedure as changing them out on a 700r4?

also, where would be a good place to order them at?

tci doesnt carry the drive gear i need.

here is what i figured on there website that i would need:

8 tooth drive gear(orange)
22 tooth driven gear(gray)
