I know this doesn't really fit here but I just want to know if anybody knows somebody with one of the above cars. I just want to know what the exact length of the rear spoilers on those cars are. I tried calling Tony's and 3 or 4 other aftermarket sellers and even though they sell them, they could not give me any info. I want to try adapt one to a B body. There are a couple guys on here who adapted a 69 Camaro spoiler to RR's and I bought one. But before I butcher my cars trunk lid I want to be sure that one of the above would work. Most likely not but I want to do a feasibility study first. I am a purist and want to keep mine all Mopar if possible first. I did not want to join the E body site just to get some numbers. I haven't had a Challenger in 30 years. I also am curious what the width of the Challenger Front spoiler pair is. I have the Boomerang spoilers already but want to see all options before proceeding. I'd like to make my 73 a little more unique instead of out of the box. Thank You
