How rare is the GMC Sierra Grande?

[sierragrande71]

Can anyone out there tell me how rare or unique a GMC SierraGrande might be? Most people prefer the Chevy Cheyenne and Cheyenne super, I have a 1971 Gmc sierragrande shortbed fleetside that I cannot find any info on such as: productions figures, paint schemes, interior options, etc...., Mine has factory cruise control, a factory two-tone paint job, upper and lower moldings, woodgrain dash bezel and glovebox door, factory gauges with a speedwarning buzzer, bucket seats, center console and lap & shoulder seat belts, also it has a/c. I bought this truck at a good price ($2,500.00) while searching for a factory big block cheyenne super, it was too hard to pass up on this deal (especially when the ad said that it didn't run and it did) If anyone can shed me some light on this mystery I would greatly appreciate it. THANKS! Sorry i don't have any interior pics yet.
