It probably took my a few days to cut off the roof. First I had to remove the caulk and lead. That took a few hours. I would say it was a cople of hours of drilling and centerpunching, and about 1-2hrs or grinding and wire wheeling. This could be a weekend job if you have the dedicated time, or an assitant, it makes it a heck of a lot easier.
I was fortunate to have a donor roof pre-removed from a donor car, so I was one-step ahead.
I did have a set-back. There were a few big dents in the roof rails onto the roof. They had a couple of creases, so I didn't know how they would come out. That in itself to about 2 days of rough/fine planishing and dolly blocking.

The replacement roof is not yet welded on. I am contemplating holding off, because temps are falling, and I have some pitting in a few areas that I would like to hit with Rust Bullit, or POR15. The skin is easily removable, it's just rather flimsy. It's clamped in place so I can fabricate the removed rusted sections.
