Lets not forget the first and non repairable WUR 0 438 140 001, substitute is 0-438-140-129 if needed. And also a non repairable throttle position compensation valve, EP/LK D1, 0438 160 001, NLA fuel filter, injector mount in cylinder head, small intake ports, first cis piston design with unique rings.......
Besides ugly rubber bumpers, front bumper mount had additional support from earlier cars, and doors had first side impact support bar. Want more? Snorkel on air box was longer than later models, unique oil tank and console (although my end of year model came equipped with later one used for '74's) couple extra wires in rear electrical panel, fan shroud only used on '73 CIS.
