Wish I’d seen this thread a while ago.
There’s several different tape colors. The Phoenix graphics kits are ultimately the best option, short of looking for all the individual part numbers on eBay and hoping to get lucky. GM separated each and every body panel into a different part number
For example.
Front fender has its own part number
Door has its own part number
An extended cab section has its own part number etc etc etc
The only major issue that I saw with the phoenix graphics kits is that they didn’t mimic the front fenders correctly (they may have since corrected this).
Each front fender tape is unique in the aspect that the lines taper as they get to the front headlamp. So a left fender strip and a right fender stripe are unique and different from the rest of the gmt400 pieces.
I was able to find a weird combination of bedside and tailgate pieces of tape to complete my truck after paint, and got lucky finding eBay nos on the front fender stripes.
Hope this helps.
