I will think of you and your beautiful Blazer every time I consult my jack instruction decal.
Seriously, I hope the auction is a bellweather for the 1969-72s. I don't think it is the majority opinion here but I believe they deserve to sell for much more $$$s than they have to date. Maybe you can push the market for those of us who feel that way.
Good luck and thanks for sharing your restoration journey with us.
