From your question I'm guessing you don't know much about gears. You might be better off taking it to a shop and letting them do the work. Setting up gears is not something your everyday mechanic can do. It takes some special tools as well as knowledge to do it right and if it's not right they won't work. Then you get to buy a new ring and pinion set.
Motive Gears are OK but not exactly high quality.

 

Im not going to be doing the work myself. Just wanted to get the parts myself so i dont get over charged

 

Most of the shops I deal with get theirs cheaper than you can because they buy bulk. Might want to check that first. Also some places won't use your parts or warranty it.

 

Anybody have any experience with any good shops that do jobs like these around new england?
