Quoted from Spelunk71:
While installing the metal apron/arch to my GB Premium, one of the front flexible screw fasteners (attaching to nut through drilled hole in the playfield) broke off. I have not been able to find this part. Does anyone know if the apron can be repaired and what the correct part is? Thanks.
Its been awhile but as I recall the bolt is flat on 1 end and riveted or bolted to the apron. I would call stern to see if the will send you one. If not check the specialty parts bins at your local Menards or similar. They might have an item like that. Last option is use an eye bolt with correct size.
