I have a 71 Challenger convertible with no VIN#, dashpad was replaced long time ago and someone lost the VIN tag...also car has no fendertag or buildsheet...coresupport and cowl stampings are there...no title or registration, came from one of the states back east where they don't issue titles for older cars..is there a VIN# list from Chrysler so I could find out what this car is..it has original V8 K frame so there is 3 options: 318, 340 or 383, any help would be appreciated!
