Some sites say it D503A others say its BS-3005
What is the original part number ?

1115315

Thanks !

The AC Delco number is D503A. This is not the same as the "GM" number. I work for an AC Delco warehouse

Unless you find real old NOS parts....
Most GM and ACDelco parts will be made in Mexico, China, etc under low bid contractors.
Your paying premium for name. ACDelco is car world equivalent to Sears Kenmore that just rebrand Whirlpool etc.

Wells make many US parts but not sure about HEI coils etc.
Stant makes many caps for car makers and move to Mexico years ago but I only use Stant cap when I can. (Most Store brands are MotoRad. Is OK but isn't exact match and may not fit.)

As for auto parts quality will very no matter where it is made.

Just because it is not made here does make it junk and if it is here does not make it bullet proof.

I deal much with part quality at work and know first hand the quality of many parts is no longer based on orrigin.

What scares me is too many people assume what is made in China and Mexico is crap while often it is as good as anywhere else. That is how they are stealing our lunch and eating it right now.

Many plants anymore employ in house Americans that over see quality control and keep them from short cuts.

Trust me if Mexico can make you 70 inch tv and China you smart phone they can make a simple auto part.

I am all buy American but never assume on quality anymore. I am in no way in support of imported parts but we all need to be aware they have in most areas caught up with us in quality and pose an even more of a threat than they have.

I know that.
MotoRad makes most part in the US and I don't use them because of problems above.
Example: Fiero Tstat cover doesn't works on all Fiero but Stant does work. GM made changes Tstat housing for 87-88 L4 and MotoRad caps won't fit. New Stant cap still fits like OE because Stant Made/Makes caps for GM Ford and others.

Don't take it personal it was just a general post. So many people on the web and get hung up over where something is made as to the quality. You just can't tell anymore as no one place is better than the others.
