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

Interesting to see Pelican still selling the ill fitting china made Hella (5DR 004 243 -111 ) ,think I payed $32 I think a way back ,now they are $52 !!!!.
Genuine Porsche one is a Beru and listed for $42, these weren't listed @ the time I bought mine sadly.
Not only are they a poor fit but my one never really worked that well,80% of the time I had to rev the engine to shut of the charge light,I didn't expect this considering I had a completely rebuilt alternator ,new loom ,reconditioned relayboard and all else in good condition .
Got sick of this and being a non returnable part all I could do was to comment in the review section ,IMO it is disappointing to see them selling them still and listed as direct replacement for original .
Bought one of 914sixer's NOS units and no further issues .
