85 Chevy Duallie Upper Bag Mounts

I have a 85 Chevy Dually. I need a set of upper bag mounts for the front. Just wanted to make sure that all the mounts for that body style were the same. In other words are the C-10 mounts the same as the C-30. Thanks in advance for the help.

I have an 82(C-30) and I think the only diffrence in a bigger (highth)spring of the heavier motor.
