[Rack Man]

I had the same exact problem...I notched out the core surpport a bit where the bottom "holder" goes to allow it to sit down a bit further.....Not perfect but not too bad...also, once you start tightening down the top brackets it will seat in the rubber a bit too....

One other problem I had was the fins on the new radiator wasn't allowing the fan shroud to sit flat...so I had to grind them down on both sides as well!

Btw, my mounts were all original....it was all in the radiator....I had my original radiator there for comparison.
