I had a '72. Almost uniquely it was as light as a feather, but that pickup is a big hot beast which will smash the preamp in any head, and is tonally 'challenging'.
Tip: If you have a look at the photo of the pickup in the eBay auction, you'll see there are a couple of flat-headed screws at opposite corners. Take those out to make the pickup a little more manageable.
(I sold mine to the bass player out of It Bites, IIRC).
