Beginning of project with original rear removed and rear floor and fuel tank removed.

View from under rear of car.

A 4-point roll bar is being used in this car. Full roll cages also available.

Roll bar installed, welded directly to new rear frame. Now original frame rails and wheel wells will be cut out.

The new narrowed rear is a Ford 8.8 inch with a 4.11 posi unit.

This is what 12 inch wide tires look like under a small car.

Here you can see the custom made engine crossmember coming together.

The original engine was a 1.9 liter four-cylinder. Now a 3.4 liter V6 lives in its place.

Here is the finished product. The car retained it's low profile and should be a real performer. The red Firebird GTA is awaiting a 383 stroker motor.
