I have heard that there are two different ways the motor and trans are set in can someone confirm?

Is there a 2wd to 4wd spacing difference in the engine location? Different firewall between 2 and 4wd trucks?
Yes, front set of holes. No 4x4, C30 Dually.

There are two sets of holes in the frame for the frame brackets depending on what engine/trans configuration is used. The 4WD uses the rear set of holes and the distributor sets closer to the firewall, I'm guessing 4 inches to the center of the dist. The firewalls are the same.
