Default Dewitts and shroud fit??

Just installed a used Dewitts rad in my Z06. It appears the radiator is sitting too far down into the rad support. I say this because the top rad posts don't reach up high enough to fit into the upper shroud. Therefore, leaving the radiator able to move around at the top.
Is this normal with a dewitts. Or is there a component from Dewitts that I don't have. I used the stock bushings. The double stepped ones are on the bottom and the single slim bushings are on the top. It appears my shroud is too tall but that can't be as its resting on the frame rail as it should.
Thanks

no not normal, do you have bushings in the lower mount?
that seem to be the only thing that could be changed.
I used stock top & bottom with no fit problems.

You may have the super charger short version if you call Dewitts likely will verify that, perhaps someone in the forum will like to swap.

I called Dewitts. According to them, I have everything set up properly. One of two possibilities. Either my radiator support is bend down or previous owner had the pin bosses machined down for their specific set up.
I think I can remedy the problem with some spacers between the bushing seat and the bushing. But I will look at the rad support. I may be able to place a jack under it and ease it up .5" and be good to go.

I have had one or two off track excursions
