Offered at my best price is a complete 1974 pickguard. Just solder to your O/P jack and play.
I bought it about 10 years ago, then added a late '70s 5-way switch. All controls sweep without noise, the switch engages each position firmly, and the pickups measure within specifications.
It is currently active in my Strat, but the guitar is being parted out. Once the body or neck sells, I cannot provide you a demonstration of the highly-in-demand tone of the last year factory production of staggered pickups from the late '60s, early '70s.
