Hey guys I know this has been posted a million times but the search keeps f'in up so i'm gonna ask again...

I'm installing 3.73 gears into a 1990 w/ AOD tranny....

1) What speedo gear do I need... 21 or 23 tooth and what color corresponds to which?
2) Where can i buy the correct size?

Thanks Guys

 

I just PM'ed it to you. Here it is if anyone else wants it.

 

Thanks

 

its in the stickies btw.

 

i keep hearing about the stickies ... what and were are they? sorry ... also what read end gear lube do you use... synthetic and what brand ....?thanks

 

You can use Royal Purple...

Also, click 5.0 section and at the top (before the threads) there are a set of threads that just stay there... they are called stickies. Click tech articles. In there is a article on the speedo gears.

 

thanks
