I've been buying up gorgar parts over the past 18 months for one of my projects.
I'll have pile of 'left-overs'.... I couldn't tell you exactly what until I'm done (Will be re-assembling when I get the playfield back from HRP) I still awaiting delivery of a few odd parts.
Defo have the original backglass (average, flaking)
Original playfield plastics (complete, I think)
will have a few bumper caps spare too I reckon
