Welcome to the forum!
The color band with the pick code identified the f/e harness to the assembly worker. the Kryta's (inline tube) like to provide such detail stickers, though there are times when such detail stickers are made up. A good example is the white labels for brake drums & the color bands that wrap around axle tubes for use on '70-72 McKinnon 12 bolts...these never existed on the McKinnon rear axles. You might try making your own color band using rub off letters from a hobby store, the correct base color of plastic, & an overlay of clear.
On the parking lamp buckets, agree the reflector area is a bright alum. It's been 2 years since I examined repro buckets from the PartsPlace, they def had wrong plating. On interior pieces, what a few fellow high level restorers used to do is search & search for #1
used condition seat covers, then if they absolutely had to, buy PUI's unassembled door panels & rear side panels, then assemble them with a lot of attention to getting a nice thin base of foam on top of their metal upper backer pieces. Now many have replaced those restorer improved upon PUI panels & bought Legendary panels & seat covers. The dielectric pleating & definition is much better with Legendarys pieces. The comfort weave on '70 & 71 seat overs, still isn't real comfort weave, but it looks better than the version PUI offered since the late '90's. On dashes, I hope with you being in Canada, you dash is in great shape, for a very nice original car, or a cutting edge Concours restoration, am not a big fan of the remolded dashes coming out of Just Dashes, just too puffy looking, & often near impossible to get the center dash AC bezel in on a '69 w AC dash.
