1967 Pontiac Firebird - Floorpan Install

Saving a '67 Firebird

By JoAnn Bortles, Photography by JoAnn Bortles

Twenty years ago, finding replacement parts for a job like this was half the work. These days, companies such as Dynacorn and Summit Racing offer complete catalogs of almost any part or tool for the common muscle-car–era vehicle. For this ’67 Firebird, all of the body replacement parts were found in the Dynacorn catalog, including the full floorpan used in this installation.

Equipment technology has also improved and become affordable for the average backyard wrench. Portable plasma-cutting systems, such as Hypertherm’s Powermax45, TIG-, and MIG-welding machines make the job much easier, even for the average enthusiast.

This is to be a full restoration, so the motor, transmission, hood, front bumper, inner and outer fenders, and rear-end were already removed. The front subframe comes off with four bolts. Two are accessed midway down on each side of the firewall, located inside two square cutouts. The other two are located under the front seats. To do this job, Dynacorn recommends removing the front subframe, and it’s easier to do that with the axle out. Most car projects have a few unexpected twists, and this one was no exception. There were a few times we had to step back and re-evaluate. This is usually a two- to three-day job, depending on how many problems arise. One more hint, take photos at the start of each step of the process. That way, if there are any doubts or questions about how something should fit, it’s easy to refer back and see how it looked before it was cut apart.
