You got 348 engine with Power Steering...looks very un-molested and original. The Power Divider is Low-Low, Low and Direct...should pull a mountain down in Low-Low and Granny...
You also have Dayton Rims, NOT Firestone RH-5's, so you're good to go! Any big truck tire shop will hook you up with new rubber when the time comes!
Is the crated up Pickup yours as well?
