Voltage Regulator, Need help finding right regulator Options

[ws6]

Help. I have gotten three voltage regulators from the normal Porsche Parts suppliers and none fit. The distance from edge of case to the first spade is .25 inches on my original regulator. The catalogs all show same regulator for 911, 914, and 914-6. The ones I have received vary from .4 from the edge to .65 from the edge all with same PN so will not fit in area to plug into. Anyone know the actual part to buy? My original has numbers on it in this order 0 190 601 006 AD 1/14V. The replacements show up as PN 901 603 206 02 Yes I can rewire, or maybe take both apart and move the guts, but trying to keep original and not have a wire harness to convert to get wires to new regulator. Thank you for your help. Tim

I was going to recommend the Bosch transistorized voltage regulator for you (043-903-803-B) but holy crap, PP has them for $250!! That's insane, maybe if they were made of solid gold. I see that Airhead Parts has them for $138.85, cheaper but still outrageous. If you can find a cheaper source, this Bosch regulator is the best one.

I have ordered the one from airhead taking the chance same company, same engine, alternator vs. generator, and same years in the hope it may work. The guy at Airhead was very helpful and measured distance to the pins and looks close.

Here's a pic of the half height, transistorized Bosch regulator installed in my car. Fit was no issue.

Thank you everyone for your help! The Airhead PN 043-903-803B arrived, fit great, and the gages appear to be calibrated correctly, so it appears to be a functioning replacement.

Does anyone know if the replacement electronic ones last more than a few years as the original made it 45 years. Thinking might buy one of the OEM replacements just to have on shelf. Thank you all again. Tim
