Well, I have two oddities to throw in the ring:
First is both a VIN & Chassis No./VIN Sticker build date anomaly - my buddy local here with another early 73 914-2.0 has a VIN 700 before mine, a chassis no. translating to being built a week before mine in late Aug. 72, but his VIN door jamb sticker (compliance sticker) shows a 9/72 date, while mine is 8/72.
Also, my chassis no. is 8/31/72 & the compliance sticker being 8/72 means mine is
the "world's fastest built 914" in one day!
