I'm swapping the manual steering to power. I've got a gear box supposedly from another 70 or 72 Nova. When I attempted to test fit it today its alignment to the column was a touch off. Meaning the gear box was pointed a touch high. Does anyone know if it is supposed to be or needs to be dead center? Also it was difficult to get all three bolts in. I was considering opening up the bolt holes in the frame just a little to be able to line it up. Any thoughts would be welcome.
