Craig,

I looked at a couple of trucks and what I found was that all trucks used stock radiator mounts for both 2 and 3 row radiators w/235's and left sufficient room for fan clearance.

I also checked my 4400 dumptruck with 216. It appears to have a 1/2 ton radiator in it? It has never overheated, even when hauling maximum loads around at slow speeds up steep hills and idling a lot.

Here is what I found.

\'52 3100 w/3 row radiator and 235 side view

\'49 3100 w/2 row radiator and 235 side view

\'49 3100 w/2 row radiator and 235 front view

\'52 4400 w/216 side view

\'52 4400 w/216 front view

The dump truck is covered with sawdust from building a play house for the kids in the top of the truck barn . . . and in case your wondering, the \'52 3100 is a runner . . . we use it to haul yard debris and landscaping stuff around the yard - it has had a hard life, but always starts and we don't have to worry about scratching it up! smile
