So I'm mid HVAC restore. I needed to fix all of the vacuum system, replace heater core, rebuild evap for r134a, etc. I wanted to post some of the things I've done, parts I've made work, etc so that if anyone else tackles this kind of project they have a little help. This definitely isn't a how-to but if you're brave enough to tackle this job it'll save you some time and money by pointing out what parts you can use as of 2018.

Nice work! I had no idea dorman made a replacement. Even better that you documented it very well.

I patched up mine with silicone sealant years back, but it probably still leaks as i know i have a HVAC leak back there somewhere.

Lucky you don't have the auto climate control with the bank of vacuum solenoids. those add a tone more possible leak points.

Nice work indeed.

One part that has been suggested before was Motorcraft YH-1463, but that's a bit more expensive. I just had it written down somewhere just in case.
