These came out of an assembly manual I bought off Ebay several years ago that is titled 1970 Full Line Assembly Manual. Now that I think about it, I don't recall ever coming across this in the '70chassis manual. The book has 2 sections, one for all the full sized, and one for the A-bodies. (The A-body section is printed on pink paper. :laugh: )
That is absolutely entirely possible. I am a little foggy on the timeframe but the car looked exactly like the one you have pictured...:TU:
