4 core lower radiator bracket install

[biohazardbill]

Well I got the wrong rubbers to put in the lower brackets so I cannot check this for myself at the moment... so to keep progress moving along while waiting for the new rubbers to come in I figured I would ask.

I had planned on using a 5/16 hex head bolt to bolt the lower cups in however just common sense tells me it will make the radiator sit high. Without the new rubbers I dont know if the rubbers would compensate for the bolt head like it did for the rivets.

So what have you guys used to secure these in place?

Thanks in advance.
