Good eye on the bumper caps :) Chalk that up to lack of sleep, now I need to go back to my parts bin, return the amber ones, and grab a red set :) Luckily, I'm stocked up on parts for 3 IJ restorations, so I'll just temporarily swipe a red set from one of them.
Interestingly, I've identified at least 2 different sets of proto ramps! I know of a HUO Proto Creature that was sold by TreasureCove here in Indiana around the same time mine surfaced. My ramps are completely different than the ones on the HUO proto game, which has holes cut on the swirl ramp and the little #86 bulbs poke through the top of the ramp. Much easier to change them in that one! My original proto ramps are pretty decent but not perfect. I have a NOS (not repro) ramp set here that is going on the proto game when I start reassembling the PF, and I'll keep the proto ramps, along with the original plastics and a few other original goodies I'm going to replace due to being worn out etc in storage so I have all the original parts. My ramps aren't much different than production, they lack locations for a couple of clear plastics that I'm assuming were done to eliminate ball traps, but are otherwise identical.
Regarding the flipper holes, I opted to leave them original just because I might want to try the flippers in both positions. You really can't see the holes that well once the flipper assemblies are installed, so it won't be too much of an eyesore.
The game will never really be 'original', in its original form this game was really too far gone to enjoy with all the cabinet damage. Pulling the shooter rod caused the front panel of the cab to pull away from the cab, and the damage also kept the playfield from sliding in and out of the cabinet. I restored a very rough cosmetically sample T2 that was very similar condition, but left the PF original and the cab art original, because there's no repro T2 cab art, and since the sample T2 didn't have diamondplate, it was not an obvious restoration candidate - and the T2 PF had some artwork differences, so grabbing a NOS T2 playfield wasn't an option for *me*. On this game, I decided to go another way, since it was so rough, the art was available, and I already had the PF back from restoration.
