It doesn’t have to be very expensive, the FR was about $100, the pickup $40 or so, did you request a black scratch plate from Pitbull? The eyelets are 25mm from Bunnings, about $4
I found the best paint to use was Dunlop dura max gloss white/black, and Hot Lips for the Schwin bike paint is very close, about $45
You will need a Floyd string retainer fir the headstock, eBay.
Use one of the kit pickups for the front and the annoying thing is buying a really nice 5 way switch and ruining it for the centre position! They are about $30
Apart from the white knob, your PB kit should have everything else you need, use their machine heads, socket, screws and so on.
I made a saltwater slurry to age non electric bits, and used acrylic paint to dirty stuff up too
Immense fun!
