We perform lots of metal repairs on Muscle Cars, and today, fabricator Adam Schulte gives us a tour of a ’67 Camaro RS he is working on in the shop. Tasks included installing Detroit Speed Mini Tubs, Classic Industries quarter panels and roof skin, and other sheet metal repairs.The car was pretty clean when it came in, save for a few obvious rust spots.
The floors looked super-solid!
A trip to the media blaster revealed more rust and previous repair damage, but not too terrible.
The rear filler panel was toast…
And the passenger quarter panel was pretty beat.
The floor was very clean except for a few small rust and damage holes, so we elected to leave as much of the factory sheetmetal in place as possible.
Here, we cut a drain hole out of the floor and TIG welded in a repair piece.
Small pinholes in the dash..
Repair panel installed and welded flush.
After repairing many of these little areas, the body tub was sprayed with an epoxy primer, except the areas where we knew we were going to remove panels for replacement.

Adam removes the original quarter panel from the Camaro. This reveals additional rusted areas, and Adam removes the original quarter panel from the Camaro. This reveals additional rusted areas, and also allows him access to install the Detroit Speed wheel tubs.

The floor is marked to show where it will be trimmed and folded to make room for the new deep wheel tubs.
The original inner wheel tubs were removed from the Camaro’s body.
Note that the trunk floor has burn cut to make room for the new enlarged inner wheel tubs.
Kevin Oeste
Adam uses a template to cut a portion of the original frame rail which will be narrowed and reinforced. This is done to accommodate the larger will tubs.
Here, the frame rail has been reinforced with plate steel, welded, and ground smooth.

Adam applies some HTP Prime-A-Weld weld through primer to prevent rust before installing the wheel tub.
Detroit Speed wheel tubs retain a factory appearance, but the inner tub is 2 inches wider than stock. This allows for a larger wheel & tire combination for better traction.
Kevin Oeste
The wheel tubs are clamped together and clamped to the car’s body for fitting.
Kevin Oeste
Adam uses the HTP Quick Spot II resistance spot welder to weld the tubs together.
A combination of resistance spot welds and MIG plug welds attach the wheel tub to the cars are structure.
Kevin Oeste
In the shot, it is clearly visible how much wider the driver’s side wheel tub is compared to the passenger side tub. Note how the rear seat brace was modified to attach to the new inner wheel tub, and also how the cabin floor was trimmed to accommodate the larger tub.
The tub is completed after some grinding and a fresh coat of epoxy primer to prevent corrosion.
Kevin Oeste
The new quarter panel is prepped to begin test fitting.
The e-coat is stripped in the weld areas and weld-through primer is sprayed on the bare steel.
Several holes are punched in the areas where the quarter panel will be plug welded to the body structure.
Soon, the quarter panel is hung on the car to evaluate the fit.

The panel is screwed in place with sheet metal screws and clamped in place for welding.

The fit is checked against the door to make sure that the gap is acceptable. When everything looks right, the panel is welded together using an HTP Quick Spot II resistance spot welder as well as a MIG 200 wire feed MIG welder.

Hi Kevin. You guys rock!
Is this topic going to be continued? Really wanted to see how you go about the roof panel replacement.
Next, the procedure was basically repeated on the passenger side of the car, beginning with the narrowing of the frame rail.
Weld-through primer…
New wheel tubs installed.
Kevin Oeste
The bare steel was all cleaned and prepped, then sprayed with Axalta epoxy primer to keep it from corroding in the future.
The new quarter panel is clamped, fitted, and welded like the driver side was.
Next, the Detroit Speed rear shock absorber cross-member was installed into the rear floor.
Kevin Oeste
Next, the rear deck filler panel was addressed. The old one had lots of rust around the window area, so it was carefully removed by drilling out the spot welds.
Here, the new deck filler panel and deck lid are installed. The fit was checked repeatedly before the panel was welded in place.
