Heater repair
The core worked fine, but should have ordered the one w flexible inlet, outlet lines. Fitting it in was a challenge, as I pivoted the dash back from the passenger side to do the Jon. I did not remove it completely. My bad not theirs

installer said it didn't fit properly
order arrived in a timely fashion, and I took it to the local garage to have it installed.

when I went to pick the truck up, I was told one of the tubes was not long enough and was at the wrong angle. the mechanic had to bend the tube in order to make it fit and also had to put a longer hose on it to make the connection, because it was shorter than the original. the entire dash had been reinstalled, thus I was not able to return the part for a replacement.
