79' Gmc K25

My 79'GMC won't turn over you can hear the solenoid click but thats it , the battery is fully charged and everything else comes on do you guys think it's just the starter ? it looks like the original one and has 62,000 on it. the other day when i was out plowing and had shut it off to move my rigs back(third time i had started it ) it turned over slow or dragging like it was hot ( had a car with headers and it would heat up the starter so it would drag ) but it started so what do you guys think ? time to replace ? Thanks for the input !

Could be time to change it. I'd take it off and test it. If it works, it may be the solenoid or a cabling/ connection problem.
