Beware,,,,the aftermkt cores have fit issues and usually the nipples are to short to protrude thru the firewall sufficient enough to attach the heater hoses
Thats why I have a few good oem cores on the shelf ,,,just in case
Agreed but...
Thats why I inserted the link specifically for the
4 Seasons heater core. I installed 1 in my 70RR and it matched the OE very closely for the fit and hose nipples length..
Just my $0.02...
I put one ( supposed to be a 4 seasons core from reviews Id received was the best option back then )
and the nipples were about 3/4" short to really get a good fit for the hoses I was comfortable with , ended up having the original recored locally.
This was about 5 or 6 years ago
