Also wanted to show the new KeyParts stampings they have of these floor pans. The passenger side I used an old TriPlus pan as it was available locally and I needed it quickly. Boy does this new driver's side pan look amazing. Firewall flange, throttle pedal provision, inner rocker portion and drain are there and the hole for the body bolt looks spot on (usually have to clock them).
Removing the old rear cab support (entire piece), I had to remove these rear cab wall brackets / supports, 12 spot welds, but as per GM quality in the late 60s I just had to remove a few and pop the others off.
Wow!
