hi umm... i have a 98 camaro v6 manual. it has the limited slip rear axle. i noticed some clunking and now the back tires lock up when it tries to go then unlock. so i took the rear differential cover off and noticed that the pinion gear has three teeth missing. i know thats bad. i was wondering how to tell the gear ratio and where to get them?

I tried to look and the stickers on the drivers door but the guy who had it before me painted over them so theres no way to read them how can i tell.

The numbers on the differential are 26041414, and on the pinion gear has the number E94 then below says CD 2.317

Also where can i buy the gear set to replace them? Im not mechanically inclined enough to set depths and spacers and all that. is there anyway i can just replace the gears as a set and be ok???

Thanks for the help
