Check out copart also. There is a 74 that someone put a hemi in up for auction now! Not many on there but you do see some different things there.

What would be a reasonable price for just a b-body and frame in good condition?

 

Well it is a unibody so it doesn't have a "frame". Depends on what b body and where you are. Not sure of what they go for nowadays. Rust free cars will be hard to find in the rust belt unlike someplace like Arizona. I would keep an eye on the auction sites and see what cars sell for and the condition.

 

I have two 1969 Coronets and they sell for less than a 1969 Charger, but more than a Satellite and Road Runner (GTX is a trim level for a Road Runner). A Coronet Super Bee sells for less than a Coronet R/T unless it is the A12 package (1969-1/2 six pack). Condiiton is the key, but there are are many B bodies in ome form or another:

Coronet
Charger
Road Runner
Satellite
Belvedere
Daytona
Super Bird

I may be missing a few. I am partial to Dodge Coronet R/T as they came standard with a 440 engine and a 426 Hemi as an option ($$$). Dodge Coronet Super Bees came standard with a 383 and usually were stripped down models with manual steering and manual transmissions to compete with the Plymouth Road Runner. The Plymouth GTX was the Coronet R/T's upscale cousin with power steering and chrome trim as well as the 440.

 

GTX was a separate model based on the Satellite that predates the Road Runner (67-71). It didn't become a RR option until 1972. RR with a 440 became a RR GTX.

 

My '72 440 RR had no GTX id at all. Likely a trim package made the difference. I still have a few items from that bird! The six pack I bought for it is running my '69 Barracuda.

 

I am referring to 1968-1970 models years. The 1967 Belvedere and Satellite are identical with the GTX being the top trim level. Starting in 1968 the Road Runner and Bevedere were identical to the Satellite. A 1969 GTX is an upscale Road Runner just as a 1969 Coronet R/T is an upscale Super Bee. Same dashes, interior, engines and the rest of the drive train.
