Frank,
Only the newer long format VINs can get the options codes from Porsche, & if you ever look at one of those, then probably Suncoast Porsche in OR (I know: OR + SunCoast is an oxymoron!
) has the best price at $10 per look-up/print-out.
For our 914s with the earlier era short VINs, you either need the original window sticker &/or dealer sales invoice listing the equipment, or you have to buy a COA from PCNA & Porsche charges a lot for often inaccurate info &/or mis-interpreted option codes (it took me 3x & a call to the customer care GM at PCNA to get it correct). PCNA offers a $20 discount IIRC for PCA members on COAs.
Even if thy get it all correct, the equipment list will be incomplete - especially as to things usually extra cost options, but included in a special model's fitment in the base price (e.g.: 911 RS/RSR, 9q4 LE, "914S", etc.).
For example, my COA even once corrected doesn't show that the Appearance & Performance Groups of options were included on the early production Aug. 72 - +/- Jan/Feb 73 914-2.0s, & which were marketed here in the USA as the "914S" by Porsche+Audi USA/NA (also 914-SC in the UK & 914S in Japan).
Don't ask more about the "914S" here, unless you want the whiners & weenies to jump in, just go read my thread on the 914S in Originality & History.
This may not be a problem with your 74 914-1.8, but I include it here for your future reference on other 914s, &/or for others looking in your topic for guidance on this matter.
BTW - the COA for my 88 Westy from the VW museum cost 1/2 the Porsche one & was correct the 1st time - although it was the longer VIN & so probably easier to get accurate info.
Good Luck!
Tom
