'77 GMC 2wd Blazer?

[alsriv2]

Hello there. I usually hang around the 67-72 pages as I am a current owner of a '69 C-10 with a 396 and some other goodies.
I just came across a '77 GMC (not sure if it is called a Blazer), 2wd, with what appears to be a nice option package. 350/350, AC, tilt column, power windows, power doors locks etc. It even has the original plaid seats/tan interior/with console. Original color is pale yellow, but has been repainted in white on the exterior. It has the hardtop over the driver/passenger area, and a removable rear roof.
I have liked this body style for a number of years and finally found one in decent shape.
Basic questions here...unusual? Rare? Can anyone share a picture or two of what the original paint scheme might look like?

The truck is not going anywhere anytime soon, so I have time to decide if I want to make this one mine. It has a clear title, and is mostly rust free being from central Texas originally.
