Authentic pickup for 1970 P Bass?

[uk_lefty]

I've got a Fender MIJ 1970 Precision reissue (alder bodied). It's a cracking bass that I really enjoy playing. It currently has a Steve Harris signature pickup that I really like and appreciate however I wouldn't mind getting it closer to the authentic sound for the year. Question is, which pickup would give me that tone? I've had a look at Fender and Seymour Duncan but suspect there are others out there.... Unless this was an era of "generic p bass tone" rather than anything distinct!

I’d try Hot Rod (who used to be Wizard) their 70s style pickup was very similar to my 70s Precisions that I had.

I used to replace the stock pickup on my Japanese basses with Kent Armstrong Alnico vintage Pbass pickups.

They sounded just right to my ears.
