Yeah, I browsed your albums and am pretty impressed with how far you went and how far you gotten it putting it back together. Someday I'd get something like that together.

I've been pretty far into my 67 and I've completely disassembled a 65 (down to the last bolt - Excellent learning opportunity!) and I have a pretty good idea why the floors rusted out. The 67 suffered windshield gasket leakage as shown in your photos - but not quite as bad as yours.

The original owner (I'm #2) though it was leakage around the doors, but when I popped the windshield out for replacement I found the evidence of of quarter-century of leakage.

Conventional wisdom is that the jutefelt under the rubber mat increased the acidity (maybe lower the Ph?) or any water that leaked in and got under the mat was trapped and led to significant floorpan rust.

When I got my 1968 130 (which spent 22-years in a dry barn), I scraped every last bit of that felt out and took a can of POR-15 to the floor.

Not sure what to tell you about the clutch setup, I was thinking you had removed too much of the firewall in order to get the pedal box in and was wondering what you were thinking of doing?
