When I made Cobra replicars- we would get people asking us to splash fenders and parts for those cars ....I have fixed a few Excalibers like that ... Most were on a ford full size (500 series) chassis. Many are pretty hacked up
They make an AMC (All Makes of Cars) look well designed
There were at least 5 copies of the Excaliber with slightly different body panels and grilles all splashed from the excaliber no two had all the same parts or interiors:
I have seen 10 copies on Ford chassis for every one real excaliber on a GM or stuebaker chassis
