Hi! stripe question
Here is my Tail Panel of my 72, the style is essentially the same as the orange car pictured above other than the different tail lights but essentially the same type of style, I bought the whole car kit (Side strips 340 numbers and tail panel) from Phoenix and installed them in the spring of last year, and yes I am extremely happy with how the car turned out with the kit I purchased from them.
If they will permit you to open your package so you can examine the rear stripes to look at them and see if they match the style of the orange ones, and if not allow the return of the kit providing you did not peel off any paper from the front or back of the decals, the stripe(s) will be visible through the outer layer of paper enough to determine if they are correct like the pic of the orange car or not. I'm banking on them being the correct ones.
