I rebuilt a similar era bmx for my daughters a few years ago and found https://alansbmx.com/ to be a great source of knowledge and parts

Cheers, looks like they've got some cool stuff..

There are some NOS Black rear Proponents on sale on eBay from the states so I might take a look at the rear I have and see how easy it might be to swap out the bolt for a longer front, then strip the black and polish...although if the bolt is cast into the ali it might prove too much of a pain..
