This Pontiac Firebird came in awhile back for a complete read end upgrade.

Our team handled:
-Rear end swap
-Torque arm installation
-Driveshaft install
-Pinion angle adjustment
-Tailshaft + shifter reseal

Every drivetrain is installed, adjusted, and verified so it preforms the way it should…not just bolted together!
