63 B radiator canted

So I set my newly re-cored and painted big block radiator in the car and its canted, by as much as .5 inch. Got pretty mad as it was all painted. Well, go to find another radiator support bracket and notice all 3 of the radiators I have laying around are about the same, with a tilt between 1/4 inch and 1/2 inch. I call up a friend and he checks his max wedge radiator, same thing, 1/2 inch tilt. So.....why is this?
Now, its NOT how the brackets are soldered, the brackets are physically different. Why would they do this? I put a rag in behind the radiator so the gap shows a little better.

Here is another shot.

as I recall, all of them are like this because the drive train is slightly canted.
if you check the fan to rad clearance, it will be even.

Are the 66-70 B bodys canted as well? The funny thing is I never noticed this before and I have had a number of these cars.

early b's have more of a cant/bias than the '66 and later due to the engine sitting in the chassis different. looks normal to me.

Looks like my 65s also.Rocky
