Tavis,.....I looked at my 71 Challenger T/A's wheel trim,......I purchased this car in 1978, from the original owner with 54K miles, in 79-1980 it was transformed into a 340/6 4spd 71 T/A, (has 77K miles currently).....all the sheetmetal is factory original, as is all the chrome/SS trim, with the exception of the hood, and bumpers......the trim on the front fenders has perhaps an 1/8" inch of body lip/color showing pass the lip trim inside the fender, the rears however look just like your photo, a good 1/4" of lip/color showing past the trim inside the fender,....while I look at this and "squeem", it is originaly the way it should look,....however, my restorations over the years, I've mounted the trim, marked the excess, and removed it, looking for a ccleaner, more finished look,.....but I know some guys are still hung up on the factory "look"
