Which CPU connector housings can be reused

The crimp connectors A1-J1 and A1-J4 just need new pins in the old housing. The IDC connectors J2, J3, J5 and J6 are best converted to crimp pins; new 2574 crimp housings are hard to find, so crimp pins can go into the old IDC housing instead. Flanged and unflanged housings both work.
