Clapton’s Blackie pickups

Was doing a home build of Clapton’s blackie. Was wondering if anyone knew what pick ups he had in there? I know it was a parts caster but I had read that the neck as a late 60s/ early 70s and the bridge was a 50s along with the middle.

So was wondering if anyone here knew any info. Would love to get that’s 70’s 80’s Clapton’s tone.
