How rare is the GMC Sierra Grande?

[gregbr]

I'll add my info on my 70 GMC C1500 Sierra Grande. It is original with 66k miles, and was owned by an elderly man, don't think he changed anything...I'm in the middleof a frame off and everything I have checked is correct numbers matching....

It is a 70 Shortbed Fleetside built 12/69, leaf spring rear, has 402/Turbo 400, Black bench seat & door panel with scroll pattern, gauge bezel & glovebox are black, has a headliner, has Sierra Grande emblems on the bed, has upper and lower trim (lower has woodgrain), complete gauge package including tach. no a/c.

Glove box SPID label and Build sheet have Sierra Grande & Custom Sport Truck. So, Are these some Super Rare Truck or what.

See my other thread for a few pics of the Resto......
