Can someone tell me the correct part number for an external voltage regulator for a 1972 Cutlass Supreme with a 55 amp alternator?
Thanks

 

They are all the same Olds/Chevy/Buick/Etc. 1119515. Now you just need to search one with the correct date code

 

Actually --- the old 1119 515 is only a 37 amp voltage regulator.... And had become VERY pricey thanks to the Corvette world.
The 1119 519 supercedes the old low amperage regulator -- and does the 55 amp, 63 amp, and even the 80 amp alternators...
I , of course , have them, if you would like...
Always best to simply call me -- Craig -- 516 - 485 - 1935...

 

Rock Auto has a selection if you aren't worried about aftermarket parts. The Standard Ignition regulator is a steal at $8.17:

Thanks guys. I already purchased one from a forum member.

 

How do you read the date code on these regulators?

I'm looking for an NOS D663 regulator for my 61amp alternator. Car was built in Oct 71. If anyone reading this has one for sale please PM me.
