I would definitely look into taking them to a machine shop and spinning em on a lathe like we did. Much easier than making your own pods that's for sure.

For the wiring, the best way to go back to factory is definitely just pulling the pins. Worked like a charm and there's lots of room for the crossovers in the void leftover from the amp.
