1965 Dodge Dart 270 Wagon

congrats on a great wagon project! yes, ditto on the gas tank draining, check the pickup unit in there, may very well need replaced. rad might need a check at GOOD rad shop. yep, pull the thermostat and place in water and bring up to boil and see if it opens. yep replace all hoses, belts, fresh points/condesor tec.
yep correct seat covers are not cheap. but ya gotta have something to sit on. lucky here in poor mans country, we have some really good country auto upholstery shops, not cheap either but an alternative if ya don't have to go back exactly OEM. they can fix springs, add foam,
