Phil, that brings back memories for me.

My favorite hammer is a Snap-on BF-618 that I picked up on eBay. It has about a 1/8" crown face and a blunt chisel on the opposite end. It works well for shrinking with a donut dolly (I use a 1-1/2" PVC coupling, sometimes backed up with a flat dolly). I don't believe they're available new anymore, and I didn't find one just now on eBay. The donut dolly can be used to shrink crowned surfaces like your fenders with a flat hammer. Robert (MPandC) clued me in in the donut dolly and the BF-618 hammer.
[on edit]Snap-on lists a BF618B, but they don't have any in stock till June '25, and they want $125 for a single hammer. eek

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
