Brian, AFAIK the only way to match the numbers on a particular 914 is with a COA, or if you can get to a PCNA booth or tech session where they have the computers set-up to do look-ups for you (i.e.: no COA printout).
Sometimes, if you call PCNA's COA 800# & tell them you're looking at buying a 914 & want to confirm it is a factory 2.0 & give them the VIN, engine & that blue ink # (see below), they may confirm over the phone, if you say you'd get the COA if/when you buy it later.
It looks to be about the 1st 1/4 or 1/3 of 74 production but the GA # towards the end (they went to GC in 75>), & the blue 022 paint number may indicate a factory exchange engine - possibly still done in the 74 MY - so a COA may also have that. Try to get the entire blue inked number too to have as a reference for that reason.
I think PCA members still get a $20 discount on COAs, & it's worth having if this car will be a nice resto, as opposed to aDD or parts car.
Curt/cabinetmaker over in Tulsey Town on here may also know a bit more about the exchange engines, but he has to do an engine swap on his DD 914 by Monday, so wait till next week to PM or email him about it.
Good Luck!
Tom
