I have a Nuovo Record Brit thread upper race and locknut. Both in gorgeous shape and would be perfect for your '75.
Wanna trade Brit for Italian?
Btw, the leather bar wrap on the '78 looks really cool - and it appears it wouldn't take much to bring it back to a uniform look. Also, if you're looking for hoods I know where you can get some nice re-pops cheap from a really nice guy
