Hi guys,
I am going to buy either 3.73, 3.90, or 4.10 gears in the next few weeks, my question is, where is the best place to get them installed at a reasonable price?

I also want to do a chip at this time to correct the speedo and get my check engine light to turn off. How much do you guys think it will be to have this all installed? How about a dyno tune also for the new chip?

Thanks
-David
