Welcome to LumberJocks!

Yes. The trunion mounting bolt holes have extra clearance, and you can adjust the position of them.

My standard rebuild process is to check the parallelism of the blade washer to cabinet before assembling the top. Typically put the blade/arbor position in center to right center of total available adjustment, and parallel to both cabinet sides. Then can normally rough align the cast iron top to be flush with right side of cabinet, and the miter slots are really close, and easy for final alignment.

The cast iron mount holding arbor also has some adjustment room, with spring washers used to keep blade pushed to one side.

Another tip or question:
Did you check the cabinet mounting flanges with the cast iron top mounts for flatness, and are they all in same plane?
While this usually doesn't impact normal miter slot alignment, if one or more corners of cabinet are bent due to abusive handling; it usually impacts the miter slot to blade parallelism as you adjust the blade angle to 45° (top is not in perfectly perpendicular to blade). A 3lb hammer and 2×4 can fix it, but might scratch fresh paint.

Best Luck.

 

When you took off the top did you notice any shims on the front corners or back. It's very important to your rip cuts that any shims get put back.
I had the a delta x5 for a couple years. I finally sold it due to a cupped top and I hated the way it thumped when I started it.
Good Luck
