Lots of stuff in the gearhead world is based around numbers and letters, right? Whether we’re talking about engine sizes and families, different chassis or body types from manufacturers, or even the real minutiae like option codes, it is all about knowing the details. If you are a GM fan you undoubtedly know many of the GM Body Designations used over the years and what the cars they represent are. A-body, G-body, etc. We have all heard them before. Here’s the thing. There are a TON of them and some of ’em we had never even heard of until we read the story that is linked below from the OPGI blog. They list all of them off and tie in the specific cars that fell under their umbrella. For example, the monster 1970 Cadillac Fleetwood 75. We had no clue it was a D-body until we read the story.

There’s lots of stuff to be learned and there is a lot of stuff to check out and shop for on the OPGI website. They have a big sale ending today and some deals on volume that can get you the price break you want and get your restoration project up and running. It does not matter if you are looking for sheet metal or high performance parts, OPGI has what you need and they have it right now!
