Bill,
I just replied to your post over at the other forum. Nice '67 C-30 that you picked up.
I checked out the pictures of your C-60. It looks like you have a good 'ol 292 in there.
Also noted that you have something rare in that truck. You have a 2-Ton with a large back glass.
I never saw one before.
Looks like a good heavy duty dump bed on that truck.
