heater core part#

[sigmfsk]

blusmbl asked me about heater cores and here's what I see in the parts catalog.

without a/c: 3780746
with a/c: 3780733

for a non-a/c car, you can get a NOS unit for $240:

or a replacement for $30:
www.ebay.com/itm/1974-75-76-1977-PLYMOUTH-DODGE-CHRYSLER-HEATER-CORE-NEW-/310205471386?item=310205471386&vxp=mtr

for an a/c car, all I found was this post from 2007 offering for $220:
www.forwardlook.net/300-archive/msg18545.html

But if you go to autozone.com and look for a heater core for a 1974 dodge monaco with a 440 U code, it shows only one heater core available:
www.autozone.com/autozone/parts/Spectra-Premium-Heater-Core/1974-Dodge-Monaco/_/N-ioqajZ91sh1?counter=0&filterByKeyWord=heater+core&fromString=search&itemIdentifier=491774_0_0_5281
and the "details" show "with a/c". So although the pic looks wrong, at least they claim that the part will fit an A/C car.
