He's right about the discs. And I didn't even notice you had a '70 truck. I think the guys who drive with the drums still are nuts. I ditched them from my Camaro in the 80's and my C2500 in the 90's. And I ditched them on my short bed last year when I did the drop. It stops now and it stops HARD. The drums were scary and I wouldn't let anybody else drive it. And I'm a reasonably proficient mechanic... and had been through the drums. But typical of an unloaded truck they locked up the rear almost immediately and made all sorts of drama.

My kid my drive this when he has his license and I wouldn't want him in it with 4 wheel drums, but YMMV.
