1962 Valiant Signet 200

I'm getting the fender tag figured out, except for a few things.
Any input/knowledge is appreciated.

A7 = 327 on the buildsheet

C3 = 443

N2 = 432 or 492

T2 = 432 or 492

Z appears to have a W under it?
Doesn't look like a sideways line stamp deal.

BDY 142 = Valiant, Signet, 1962 (it's not a Plymouth, it's own line, who knew? I think I knew this, at some point in the past)

TRM 581 = I know it's blue, buckets, just not sure exactly what it means.

PNT DD1D = I know it is VALIANT BLUE METALLIC, is the extra D upper door frame paint, or buffed, or two tone?
