Good luck! I had a hard time two years ago finding all the trim for my limited. I found a guy at the nats that had a ton of NOS trim. I'll look to see if I still have his card.
My brother has used both of them Quik and is very happy with fit and quality for his 66 Nova SS. I'm not sure just how many parts they have for T/Types and GN's.
Poston in AL has some new chrome trim pieces listed in their latest catalog. Might wanna give them a call?? Boneyards are full of chrome trimmed Regals in SE US especially here in GA. I have some spares put away for myself. Good luck!
