I haven't fitted the slide to the frame yet. As long as I don't have to take too much off the deck of the frame in that process, I think I'll be alright. If I need to take more than a couple thou off, I figure the ejector will drop down too far and the ejector pin notch will have to be re-drilled. That might turn the drilled notch into more of a slot, leaving the ejector to slop up and down on the ejector pin. Potentially.
