When the machine was new, it came shipped with RED brackets that connected the axis to the machine base. And I believe there was a RED bracket for the Sub-Spindle casting. Most people lost these brackets. If you have them, you will be able to see where they go by lining them up near the axis motors and the bracket near the Sub Casting.
One T42 we bought used:
I just went to Home Depot before the machine shipped and bought some 2x4's, WD-40 and shrink wrap.
Cut a 2x4 to fit tight between the Sub and the Main Spindle. Came down off the Turret with another 2x4 into the Sub.
And screwed in all together tight. Soaked the inside of machine with WD. And then shrink wrapped the entire machine top to bottom.
Made it fine to our shop 350 miles away. Boards were still tight and machine was good to go.
NOTE: Your 1997 might have absolute encoders. If the bats have gone dead, you will need new bats and also need to do the zeroing procedure.
I can help you if you need.
Good luck!
