don't forget bmx was dead during 91- 96 ( the x games put it back on tv and gradually it picked up again) so parts were produced smaller quantities during
the 'dead years'- and most parts were used and passed on to others so hardly any parts survived NMS- new mid school.
back in the 80's it was all mass produced so that's why there used to be loads of NOS floating around.
good luck to whoever does find any good mid parts.
