Meanwhile, a new rear axle assembly was finished. The housing is a narrowed Currie unit that has been fixtured in preparation for welding the Detroit Speed brackets in place.





The center section is a Currie 9+ nodular iron unit, stuffed with a Detroit TruTrac limited slip differential and 3.70:1 gears, with 31 spline Currie axles.

Metalwork nearly complete on driver side wheel tub.



After considering the filler covering rust repairs in the trunk, it was determined a new trunk center pan would be the best course of action. The section was removed.





The new center was ordered from Classic Industries and installed. The perimeter was TIG welded with an HTP Invertig unit, and the center supports were resistance spot welded using an HTP VersaSpot 7000.

The leading edge was MIG welded to the crossmember per the Detroit Speed instructions.



The perimeter was metalfinished to blend with the trunk floor.



The increased wheel tub size and narrowed frame rails are more visible from under the car.









The rear axle assembly was lifted in place to determine the location for the upper shock mounts.



The new Baer brake rotors are test fitted as well.

At this point, we turned attention to the front of the car. The stock GM Camaro subframe was going to go in favor of a Detroit Speed Hydroformed subframe. We elected to drop the stock subframe complete with 540 cube V8 with the front sheetmetal in place, with the goal of not having to remove, reinstall, and realign the panels if we didn’t have to.



The body was placed on the lift and protected with spark paper. All the fluids were drained from the engine, the wiring harnesses were disconnected, brake lines separated, coolant hoses pulled, the A/C charge was evacuated and the lines disconnected. The body bolts were loosened from the subframe, and the car was carefully raised up off the subframe.

In the doghouse…



We’ll clean up the big harness hole with no grommet, and sheet metal screws in the shifter hole / transmission tunnel.
