Rubber bushings for aluminum radiator?

[J-440]

Was wondering if I need some rubber bushings for my aluminum radiator mounted to the support. I've heard that some radiators crack with all of the heat cycling. On my car, I have 4 points to where it is secured from welded on tabs. The bottom is not sitting on anything, it's just flush mounted to the support. Thanks.

I always add at least two lower rad mounts to set the rad on. To prevent the welded tabs from work hardening and then cracking the radiator's weight needs to be carried by these lower mounts. Use the two upper tabs to hold the radiator to the support. I get most of my lower mounts straight out of the junk yard. The rubber cradles are usually laying on the ground or still in the car if the rad is gone.
McMaster Carr has a good selection of rubber isolaters in various sizes for the upper mounts.
