Cool, that is interesting. Never took that in consideration. So one side using rubber was enough to handle the expansion? wonder why not both sides.

To prevent the expansion of the brass/copper radiator (which is a lot) from breaking either the bolts or the radiator flanges. Early Mustangs, for instance, clamp the radiator at top and bottom in rubber coated "u" shaped brackets that allow the radiator to expand and contract freely.
