I'm in the process but won't have answers for at least a month
I have a Summit 27"(?) - I did another thread here on it and mounting options, but don't have time to look right now. You need to watch the height, though. Keep in mind that a radiator that wide will probably be sitting on the frame rails and your battery will need to go to the trunk, which I had planned to do anyway. My fill cap is going to be very close to hitting the hood - I measured with a tape measure from underneath and my girlfriend closed the hood on the other end of the tape measure. I think I posted the measurement for a '70 on that thread from frame rail to hood. Depending on where any interference is, I will either notch the hood structure underneath or the frame rail, if there is any interference at all.
