1966 GMC 351E Rare?

[cbrwags]

I just got a pickup and would like to know if it is rare. The truth is I have 2 pickups, 65 chevy that is clean, and the 66 gmc that has a little rust. I plan on selling one and working on the other. I want to know how rare this gmc is before pricing it, my 65 is a frame off and is a nice c10 lwb, the 66 gmc needs more work but might be a better truck to restore?. Ok, 66 gmc has, bucket seats, padded panels, power brakes, lwb, vacume gauge (dont know if it is stock), chrome grill and badges, 351e engine, 4 sp trans. vin# 1002zf14866a. I would like to know how many of the 66 gmc's had the 351e, and bucket seat options.
