Yes. In the photo (Edelbrock carb with Edelbrock adapter)
I had to trim the base of the adapter because of interference with the kick down cable attachment point during full throttle.
After cutting off the interference point I painted it silver. They come anodized gold.
Here is one of theirs on a Gen2 Hemi single 4bbl..
Same as a RB. I used a cable kickdown but the factory set works too.
You may have to use a Edelbrock or Holley Mopar throttle adapter.
Not sure what EZ Fast uses.
Yes Royal Monaco. Dodge in the same years had a Monaco that was a B body 2 door.
They had several versions such as the 2 door Coronet,Charger Sport,Monaco.Those are what I remember they may have had even more. Chrysler was doing strange things in the mid/late 70's being on the brink of bankruptcy.
I follow the Mopar Market closely. Mostly the lower end of desirable Mopars. If the car was original and in #1 or #2 condition, Maybe $10K for a C Body.
It is unfortunately that modified cars bring much lower value. Unless you REALLY want the car a offer of $8K is not out of line.
Nothing is...
Look up Dr. Diff, He is a Bodies member and deals in Mopar rear axle parts to complete housings.
Possible you can get a better deal. I have been dealing with him (Cass) for years.
