I have a FP panel with pipe and no room for another along side. I asked about a retro kit on a couple of forums about a year ago and didn't get any response. Today there was a FP discussion on another forum and Pete put up a link I was able to follow and get this info on standard and custom retrofits for FP's and some others.

Got a number for Cuttler-Hammer Eaton Flex center and they say they make custom retro fits for residential load centers. They have some standard kits but it looks like I'll need custom.
Ballpark for my custom was about $400 +breakers. Seems pretty reasonable to me. The number at Eaton is 800-330-6479. I spoke with Steve. To order you'll have to go through a C-H distributor but your distributor might not be aware that this is available as mine was not. You'll need the 3 box dimensions, number of breakers, etc. to get a ballpark. I'm excited about getting rid of my FP's at a reasonable price.

I used several of those kits to replace flush-mounted Sylvania/Zinsco panels. Slick as a whistle. Quick delivery, too.
