Can anyone tell me the difference in Excalibur's and Classic roadsters I have one CR and another partial that the guy furnished some info to me showing it was a JAC 427 no tittle just bill of sale It's red with white strip had been wrecked and new front end put on missing parts trying to figure out what I have other than a little difference in door cutouts everything appears to be same. Frame is same except for one has brackets for strut arms other doesn't. Don't have enough parts at this time to finish both of them but, trying to find out what I got.
Thanks
