I bought a stock clutch cover from Retro, and it was a stamped 2 layer steel cover. The hardest part for me was figuring out how to line up and mark the holes, I ended up making up a grid on the face of the cover and drilling 4, 1 1/4"
holes. I extended the grid from the top over the sides, and drilled 8 (i think) 1 1/4" holes around the edge. I used a hole saw and a drill to cut the holes, and on the top of the cover it seperated a little from pushing too hard on the drill, so when I was finished drilling all the holes, I squirted a little JB Weld into the split and clamped it for a couple of hours. It turned out really good, I ended up using black automotive paint to finish it, the only thing that I wish that I'd done differently would be to sand it a little better, you can see where the edges of the original paint were left, I may repaint it later if I'm so inclined, but I think that it looks damn fine. Sorry this post is so long you can PM me if you have any specific questions.
