I know Philco had radio-counter displays so you could grab the replacement bakelite block you needed, but they apparently never sold many of them.

I restuff bakelite blocks, but I don't use the heat gun/oven methods, I just pull the block, and chisel out the guts with a small screwdriver. It takes about two minutes to get them all cleaned out. One of the blocks in my 60 had two mica caps in it, so I just let it be, since the other micas in the set tested fine.
I have some three-conductor cloth covered repro. wiring around here somewhere too. The guts are popping out of a couple of these already so I'll try your technique. Hot stinky tar isn't much fun

There's also a 5-section cap in a metal box. I hope that won't be a pain to restuff.
I hope I won't need to do an alignment.
I'm amazed at how many trimmer caps there are. Something like 7 in total.

Thanks for the suggestion. Once I get it working, I'll do a comparison with and without a bottom shelf.
