Replacement Panels - 1954 Pontiac
Rocker Panel
The rocker panels, bottom of the rear quarter panels and the bottom of the trunk lip were rusty and
needed replacing. I had purchased replacement panels from several sources
a couple of years earlier
(as I found the funds, I put the money to good work before I spent it on other things like food and
necessities of life!). While I was at it, I figured it was a good time to replace the square gas cap
lid with a round one off of a 1980s Chevy.

Here's the driver's side rocker panel - bent and rusted

The replacement panel and old rocker primed cause I was tired of looking at a rusty green car
I spent a lot of time marking where I wanted to cut. I left about 1/8" more than necessary so that I
could fine fit the piece. I found that an every day jigsaw cuts sheet metal very well, straighter and
faster than typical bodywork tools like a die grinder or air chisel. Expect to break a lot of blades
though - you can keep reusing the shorter and shorter blades though.

Used a jigsaw, die grinder and 4 1/2" grinder to cut out the old piece
I don't have a picture that shows the complete side which shows how much was cut off. I measured and
marked and cut off the rocker panel, 8" off of the bottom of the quarter panel, 4" off of the
complete wheel well lip and 8" off of the rear of the quarter panel.

Finished rocker panel

Driver's side door jambs finished
The rocker panel was MIG brazed in place which worked very well. I used MIG brazing because the
temperature is cooler than MIG welding by about 500 degC which means less chance of warpage and
burn through. It worked very well for the rocker panel as there are lots of bends in the metal to
prevent warpage and the metal was very thick and solid where I brazed. Filler was used to smooth out
joint.
Quarter Panel
I don't have a picture of the quarter panel cut out unfortunately or maybe fortunately, because its
quite scary when half the panel is missing. I had a very difficult time mating up the three patch panels
together. Here's what I started with:

Lower front of the wheel well

Rear of wheel well
