In case you haven't bought a fuel tank yet, I can attest to Van's as being a very good seller. I've bought a few tanks from him, most recently for my 1965 Imperial convertible.
Very nice car, especially like the colors! The brake booster is a Midland-Ross dual diaphragm, specific to Imperial and not found on lesser Mopars that used Bendix boosters.
I've used Power Brake Exchange (Booster Dewey) in Mountlake Terrace (Seattle, WA) to rebuild my boosters for years...
Very good review of this Imperial, thank you for sharing! On a side note, the coupes didn't have pillows on the interior C-pillar like the 4drs did, they had just the plain sail panels pictured (good pics too). Also, the six-way power seat controls were were not mounted in the door during these...
Unfortunately this car was parked for 30 years in a muddy lot, along with about 60 other cars from what I was told. Lots of rain here for half the year ☹️
