Brent,
FYI - IIRC by the time the 914's came out in 69/70, all of the US dealerships had changed to "Porsche+Audi" - with the base VW dealership that used to sell the Porsches on the same sales floor alongside the VWs before that, now becoming a stand-alone & separate dealership. Some VW dealerships which used to sell Porsches, refused to pay the bucks to build & open a separate Porsche+Audi dealership - so they lost their Porsche franchise as a result. Ergo, you'll probably want to stay away from VW only dealership frames.
So you'll want a frame which is either "Porsche+Audi" or lists the "twin dealerships" in some way separately as "Porsche+Audi" & "Volkswagen" on the frame.
I just saw the old Chick Iverson parts VW Bus restored at the local VW Jamboree (now it's Newport Porsche under the Power Automotive banner), which showed the dual logos nicely but can't recall if they were over-under or side-by-side? Didn't take a pic either!
Go to the Porsche dealer locator online & enter in a zip for SoCal & NoCal, then try calling the dealers, cuz sometimes they may have old vintage ones used or nos on hand to sell, or may still be using the same design today. They may also know of customers with old frames that they'd like to sell also. ... worth a try to a few dealers any-hoo!
Rich, I grew up 6th - 12th grade in San Diego, knew Balboa Datsun well, & had an HS buddy who worked there - but had never heard it was the 1st in the USA. ... very interesting tid bit!
> Same applies to try calling them, if you haven't tried that yet.
I don't need a vintage dealer frame, but need to reproduce my 70's pot metal frames with "It Takes Leather Balls To Play Rugby" on them,
.... cuz the paint shop who did my 85 BMW 325e a couple of years ago broke my last intact one!
BTW - we
did use leather -
not vinyl - balls back then, & it loses something with "Vinyl" in that slogan today!
... it would sound like someone doesn't know how to use a condom properly or who had some sort of odd scrotal transplant, etc.!!
