...... due to an overfull garage and winter.
.....
Well, I'll bet MY overfull garage is more overfull than YOUR overfull garage!
My projects also barely progressed over the winter. I did fab up some patch panels with a bead roller and shrinker/stretcher. New techniques for me so it's been slow. Last summer my 66 vert got a floor and trunk. Did a bunch of blasting and primering too. Next I'll be piecing the rear qtrs back together.
Do you have a final plan for the Special, or are you waiting for a more suitable car? I'd suggest taking the A/C off and utilizing the firewall/cowl openings for a cold air intake. There was a 68 GS option like that, and I think Doc did that too.
