As a test you can pull out the gib lock screws and replace with a bolt and a nut and adjust the gib as if it were a screw adjusted gib. This only gives you 2 adjusment points, but will tell you what you need to know. My G0704 has been running like that for years due to a tapered gib that doesn't fit right.

Thanks for the tip. I'm doing something similar. I got rid of the original adjusting screws and made a spacer that fits the gib screw counterbore with just a few thou of clearance then use a socket head cap screw for adjusting. This gives me slightly better contact on the end of the gib.
