Mine is a 9/73 so here goes.......
Seats should be twin rail so might even just slide straight in, steering column switchgear/ignition barrel/steering lock (this doesn't just bolt up though), disc brakes with wheel bearing matching and a caliper mount, interior trim (armrest bolt-holes are a bit different), the heater fan works great down the back to "push" the heated air, all the 12V stuff like mounts/globes/regulator/generator, the SSC gearbox ("L" Bug box) is the strongest Beetle box out there and you can adapt the whole IRS to the '66 if you want, the 4-stud wheels onto the 4-stud brakes that bolt up to the '66 rears, the speedo is 160kph not 140kph (mine is at least) so you won't break the damn thing with only a piddly little 1641 on the way to Leonora for the races when you're running late.........😀
Lots of stuff, have a look over when you get it next to the shed.
If it's a '74-up, then some parts are different, but not many really, you just need to be creative sometimes.
Seats will not fit. '66 is the "L" shaped rail.
Brakes will not fit easily as '66 is king pin.
Speedo will not fit as '66 is flat vertical face.
