Free C10 1966 straight six swb fleetside

[mrp82391]

Was told I could have this truck for free with title and keys. One owner. All of the parts seem to be there except the passenger side mirror is different. straight 6 3spd on the tree. Not sure if it's worth fixing up, the floor pans and sill are pretty rusty. I'm not to familiar with chevy trucks. I was told it ran when he parked it ten years ago. The only dent is on the roof and its not creased. Looks like the most basic model one could purchase for the time. Driver side window regulator is locked up. Small crack on the windshield. Thanks for any help!
