Joe...they will likely have bumpers to just swap out with you. I took my bumpers from the yellow car over to be done, and Porter had plenty in stock for Challengers at that time. BE SURE to open the wrapper and check them before you leave! I looked at one, and it looked fantastic as is per usual with Tri City. I left the other one wrapped, and when I unwrapped it 6 months later to put it on, it was a 72 bumper with the jack slot in it...even though the wrapper was marked 70-71. They gladly swapped it out for me, but I had to make an extra trip over. They might weld the slot up, but I don't think they will give the lifetime warranty if they do. Porter told me they stopped welding up holes, but that was 4 years ago and things may have changed since then.
