Brent, You have 2 nice examples of older rigs, what are they worth???......
The Farmall M,, Run of the mill, nothing special to write Mom about. Real short on rear rubber, 10%. A single Cotton front, 75% rubber. Single pipe, flip-seat assembly... Not a Plus in anybody's book! A decent paint job, not spectacular, sure-enough not Show Quality the tractor will bring $1500 all day long...+ - $300! The Rear tires will dictate the worth at present time.
What I see from your single Pic
64,65,66 Series GMC 1500. Short narrow, No V6 badgeing on hood, So No V6 under the hood Decent paint not spectacular! Paint looks the be the Correct,, Lt Yellow for for era of truck I Do Like! Whoever painted it last Painted the Grill the Body color...WRONG they came white or chrome, No 2in white band painted around the Grill area, No Flat Gloss Black behind the grill, Wrong Hub caps, You have a GMC Please get a set of GMC Hub caps don't try to make it look Like a Chevy, The Jimmys Were truly Unique.
