ECE Engine mount pics and tips ?

[68MoneyPit]

I have a set of engine mounts from ECE to install my 6.0L. I guess I have an earlier frame with a wider top rail that will need to be cut out in order to make room for the 73-87 style brackets. the problem i am having is that when i cut out the frame to install the brackets, they match the top rail of the frame but the angle does not match that of the front crossmember. Also I thought I had read that I would be re-using the hole that is already in the crossmember to bolt down the back of the bracket to the crossmember. That hole is not even close to lining up with the bracket. If I line the bracket up with the hole in the crossmember and with the angle of the crossmember, it picks the top of the bracket up about 3/4 of an inch above the top rail of the frame.

Long story short is I'M LOST and most of the pictures I find on here are pictures with the engine already installed which does not help.
