I recently purchased a 1971 914/4. I'm interested to know how the chassis number and the engine number correlate. vin # is 4712912864 and the engine # appears to be W0107102. The colour code is L21E. Car is most definitely Tangerine....I kinda like it.
If any one could shed some light it would be most appreciated as I plan to completely dismantle the car and restore it to factory original specs. Thank you Adrian

Full Version: VIN and Engine Numbers
Hi Adrian,
The only way to find out if it's numbers matching, is to contact Porsche Cars North America (PCNA) from the Porsche website's Classic section under Certificate of Authenticity, then call &/or send the form & fee for a COA with your VIN & Engine & chassis #'s.
If you have the original window sticker &/or dealer invoice when new, then you can send a copy along & IIRC you get a discount for the former - & they are less likely to screw it up with PCNA's errors. If you're a PCA member, then they also get a discount on the COA.
To decode the chassis # - Look on your VIN sticker in the rear driver's door jamb for the date & get that year's calendar online, then use the Chassis # on the Karmann Plate in the front door jamb with the paint code (in the top box) to get the build date of the chassis....
Chassis No.:
XXY95ZZ
XX = week in year - use the calendar above to count weeks
.... starting with week #1 even if only 1/1
Y = Day of Work Week 1-5 = M-F
95 = Karmann Plant > 96 or 97 would add 100 or 200 to car # @ ZZ
ZZ + Car # built that day
The VIN sticker is the Month/Year it rolled out complete for US-DOT importation (same for USA built cars)
Google for the PPG Paint Chip Library, since they keep them for the VW & Porsche Cars, & L21E is a VW paint code used on 914/4's so would be the same color either way. IIRC they also have a section for the paint mixtures too.
Use Jeff Bowlsby's 914 website & p914.com & 914 info on here at the top + the Originality & History Forum here as research resources, so ytou know how to do it correct - since that's what you said you wanted.
