I've done a ton of gear installs, people on the local houston forums can vouch for me if you want to check em out (
www.westsidemustangs.com, www.pomoforacing.com, and
www.htownracing.com).
I charge $150... you provide gearset, 2 quarts of Mobil 1 gear lube ($6.99/qt at AutoZone).
I'll have time early next week if you're interested. I'm on the north side of Houston in Spring.
PM me if interested.
Regards,
