Mine isn't a Javelin. From 68 to 70 AMX and Javelin are different cars. The AMX shares much with the Javelin except it is a foot shorter with no back seat. 1971 to 74 the AMX was a Javelin option. Both cars are the same body.
In AMC world the 71 to 74 are called "Humpsters" for their Humped fender wheel wells.
I am glad to own the one I have but would own every example of the RWB cars, If I were a rich man. lol
