Need a little help on a blazer....

[71 super]

I stopped and looked at a blazer today. It was 4x4, original black top unit with dealer installed cruise. There were a couple of things that were off ad I just want to check myself before I procede with an offer... 1) the truck had lower wood grain, and upper narrow trim like pickups - is this upper trim a add on? 2) the dash was woodgrained as a super and so was the glove box door which had a 72 super emblem on it. The Spid was in place on the door and the vin matched the jab and the frame. The spid calls for cheyenne equipment, but I thought on blazers that meant the CST emblems on doors and glove box door. It has dealer air, p/s and auto and somewhere along the line someone installed a 454 (guy said it was original) . Let me know what you think, and sorry no pictures. It used to be blue, but is now a black urethane of some form or fashion.
