Options factory or dealer

[Dan72cst]

Who's the expert on options?

I purchased my 72 CST blazer from the original owner with the protect-o-plate, manuals and receits and it has a lot of things that aren't on the glove box sticker. The old guy told me that this stuff was on the blazer when he drove it off the lot. These are things that I have heard people on this board talk about as factory or dealer installed like roof rack, rear tire carrier, brush guard, front axel support, compass, roll bar, interior rear side panels etc. There are also some items that haven't been addressed as factory or dealer installed like a front axle engage light, dome light on roll bar, passenger entry assist handle, level-o-gauge, bedside tiedowns etc. Now some of these things I don't think are dealer installed, but others I wonder about. There is another wierd thing, my blazer has power steering and power brakes, but only one of them is listed in the glove box. I think it was the steering.
