The Warlock in the pic is a clone. They were made in the 70s not the 80s like that one.
Plus the Warlocks didn't say "Warlock Express Truck" on door.
At that time there was alot of emissions crap added to engines which created headaches.
Emission equipment was basically the reason for the Lil Red Express, or at least why it was a truck and not a car. Cars were loaded with everything but trucks weren't yet. Plus some mods could be made to the engines without having them re-certified. The '78 had no catalytic converters but unfortunately the emissions regs changed for '79 and those had cats.
I owned a 78 Dodge Super Coupe with the 360. Very fast for a late 70's car.
Cool, I've always like the Super Coupe look. It wasn't one of the more rare "kit cars" was it?
If the spot is by the door and not towards the wheel opening you may have to get the support on the back side of the fender patched up. If the carpet is out of it look along the floor on the inside where the weatherstripping is mounted, real common place for rust holes that you can't normally see. Also check out the radiator support down by the body mounts. Seen a few trucks that were rust free except for the rad. support.
Its doesn't look to be in to bad of shape. You say he still has the original rims for it? With the center caps?
Another bad spot for rust is the rear cab corners. My '78 W150 was totally rusted out underneath the corner but showed nothing from the outside.
I have a friend with a '78 LRE so I've gotten to play with his over the years. Unfortunately, I haven't seen him in a while and due to the OP's location, plus the fact that a mutual friend has a '72 RR, I'm wondering if the '78 mentioned is my buddy's?
To VintageIronCollector: If you end up with this truck let me know. I purchased a good bit of govt. surplus Dodge truck stuff for my '78 and might be able to help you out if you need anything. Plus I'm very curious who it belongs too.
