Anyone with a K20 or K30 that can get me a few dimensions? I need the frame horn dims at the front of the truck (without the bumper brackets). Plus, I need the rear frame width minus any bumper brackets.

Thanks.

what year?

73 to 87.

If you search under posts I started, I was looking for dimensions and someone linked me to a site with full blueprints pretty much for 73-87

I found it.........
