I will keep an eye out on the various old school sites I frequent, though more of a Mongoose man myself as that is what I raced back in the day.
They don't come up very often but you do see an odd one now and again. I don't know whether you have dabbled in old school bmx before but you may need to change you road bike shorts for some long trousers as the pockets need to be way, way deeper
Though looking at the brochure again that is more 90's mid school, street style rather than 70's, 80's racer so should be a bit easier to source.
