Peavey Dyna pickup replacement

[Cnivek61]

Hello been searching for a few days now for info on replacing Super Ferrite Pickups in a 4 string Dyna. I picked up just the body and am trying to find out what my options are and maybe what I'm getting my self into before going to far.
The Bass has been sitting for a few years and been gutted for parts by previous owner, I was hoping to find the original style pickups, but think I may find the holy grail first. So any ideas or info would be Hugely appreciated.

I know the OP was 4 years ago, but if you are still looking for Super Ferrites, look up Derrick Cook on Facebook. He works for Peavey and periodically posts odds and ends from the Peavey warehouse for sale. He told me recently he has Super Ferrites available.
