yea, I will let you know. like freez said. If you leave the stock hole in the slide the same. you can allways plug the hole/holes that you drill. if it is not working to your satisfaction. I will just try one or two more of the same diameter as the stock hole.
did you say you are a deisel mechanic? what do you work on? just curious.

 

I served my aprenticship on hgv articulate trucks, then moved and worked on hydraulics for a few years before going to work On rigs, not the kind with wheels, there is a picture of what I fix for a living in my pics page.

i have worked on buses a couple of times, everything under hatches or behind panels was a bit of a pain
