Rear End Rebuild Questions

Well, my stock T-Lok is not doing its job, so I want to put some 3.73 gears in it and rebuild it. I would like to get the job done by Drive Train Specialists (www.drivetrainspecialists.com) because I live near one of their shops and I know they will do it right. The only problem is they charge $58 for clutch packs and $140 for bearings and seals throughout. The labor is $225 (decent price IMO). There is no way I am doing this on my own, but I was hoping to get a cheaper price for the rebuild kit. I know clutch packs are about $50 no matter what, but as for the rest, Summit Racing (www.summitracing.com) sells a bearing/seal kit for $81, part number SUM-G7819 . Has anyone used this kit? Will it have all the stuff I need (besides clutch packs and friction modifier) to get a complete rebuild? Also, I have found FRPP 3.73 gears for about $160 on ebay. Anyplace cheaper for the ford ones? I just don't want to pay over $550 for a rebuild with gears. But if that is about as good as I can get, I will just go with it. Thanks....

Well I want to get everything replaced except the axles and diff. I'd rather have it good as new than just do the gears, then have to do it all again in a year or two cuz the bearings are wore out. Oh well I guess you get what you pay for. I just really wanted to get some other stuff for my car before summer (like U/D pulleys). Guess I'll have to wait until I start my summer job again... Thanks for the help, btw.
