both of my fastbacks (65 & 69) had the body color on the trunk side of the trap door. the 65 was definatly that way from the factory. the 69 is also a metchuchen car,like yours, but it was painted once before i got it. so i couldn't say for sure if thats the way it came out of the factory. i'm guessing it was. sorry if this doesn't help much.
