By 70s glam I assume you maybe mean Sweet, Slade, T Rex, Bowie, Suzi Quattro, Mud, Queen, Rubettes, Gary Glitter
High gain pickups weren't really around in the early 70s so you want to look at the vintage end of the range .
A lot of LPs used at that time had what are referred to as Patent number pickups because they had the patent number stamped on the bottom of the pickup
Closest in the BKP range is the Riff Raff
You could also use a Mule
Or if you want a touch more oomph then look at the Emerald as that kind of still fits the bill
(Black Dog and VH2 will work but are less obvious choices, and you could get away with a Crawler if you neededthe guitar to be more hard rock ...
