[69 Z11]

I want to change my stock 2017 convertible ZL1 silver calipers out for the 2018-19 A1Z red ones. I understand that the calipers are identical except for the color and that this is a straight up bolt on project. I would then hopefully sell my ZL1 takeoffs to someone upgrading an SS. 1st, is this a correct and workable plan? 2nd, can someone verify that these are the correct part numbers? 3rd, where can I get them the cheapest? Thanks in advance!
