What are these PW regulators out of? E-body? B-body?

I had these stored for years along with some E-body rear window regulators, however, they are different (or at least lack the pivot bar that the Es have)

So what are they out of? '71-2 B-body? E-body with pivots missing? Other?

There are no part numbers stamped that I can see

Thanks in advance

And from da udda' side....

Those appear to be E body hardtop rears but they are missing the arm which should be riveted to that oval slot... (It's a JUMBO rivet)

May as well add a picture... Everyone likes pictures...

OK - that makes sense because otherwise they were identical to the other ones I had.

At least I have some manual regulators that I can pilfer the crossbars from.

While I'm asking - would you know the part numbers/stamping number for the front regulators? I have a couple of suspected E-body ones here as well

Thanks in advance

As always, pics help: Here are the front ones

And from the other side

And a closeup of the part number.

Those are not them... The give away is they don't have a double arm that attaches where the motor bolts up.. Those may be 71 B body....

FWIW I can't verify the accuracy of this list but someone posted it years ago & I saved it...

1970 B-body ft. - 2999682/3
1970 E-body ft. - 3548530/1
1970 B-body quarter hardtop 2583764/5
1970 B-body quarter conv. 2583854/5
1970 E-body quarter hardtop 3454108/9
1970 E-body quarter Conv - 3508210/1
1970 C-body ft 2945996/7
1970 C-body Quarter hardtop + conv. 2945560/1
1971 B-body door - 3548750/1
1971 B-body Quarter - 3548610/1

.

So by those part numbers, what are those regulators off of?

I ran into the same problem as I wasn't able to find the numbers in my 70-71 parts book.

It would make sense that they're '71-2 B-body based on the part number prefix and also the source that I got them from many years ago. But it would be nice to confirm.

The rears are definitely E-body less the rivet, so thanks 1 Wild RT

I'm pretty sure 15 2 is the date code...15th week of 72.I have a 73 SSP with pw's...when I get a minute I'll check.

Thanks!

Are all 2-door B-body door glass/regulators the same from '71-4 (at least within a model range such as Charger or Satellite) or are there changes similar to the 11-hole to 9-hole door glass on E-bodies?
