Aluminum Radiator Mounting - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What are you all doing to mount square tank type aluminum radiators using the stock V8 style U shaped saddles with the rubber inserts? I shaved down the rubber inserts, but don't like that the metal part of the saddle is now real close to the tank, and the fit is not so good. I reached out to both Champion Radiator and Brothers and while both understood the problem, neither had a solution.
I know somebody out there has figured this out.
Thanks,
Tom

I also fabricated my top mount (mine was missing from the previous owner, so I had to make one anyway).

I had to add about 3/4” to the top mount and then I used thinner rubber pads for the bottom.

I fabbed a bottom U channel by welding up thin angle iron. Modified a stock upper mount by cutting and welding. Applied some rubber sheeting to both for cushioning via adhesive silicone.

i used an aluminum rad from RND FAB.bottom fit in the original saddles but
top was wider.i bought a spare top mount,sliced it up and made a bigger one out of two.used original rubber .looks original.all ideas above work good too.

Some great info and ideas. Of course not as easy as expected, but I'm used to that.
Thanks to all who replied,
