Im sorry to come off rude, but you should eithier ask a professional in real life, since its easier to not get confused. Also, I hope you arent planning to do this on your own, since its not a 'simple' DIY. Requires pretty tight tolerances and special tools (dial indicator, etc). I have pulled trans's by myself + friends and all but I still dont dare touch the gears without someone who knows how with me.

 

^o i know lol, i wouldnt trust myself with this project. one of my good friends is a master mechanic and has rebuilt trannys and has done lots with gear work

 

Is there anyplace where I can still get 4.57 gears?

 

yea thats a good question, cause i wanna get some gears here soon.
