Yes find the smallest drill possible. A friend of mine had one. I did have to buy a bit though. Can't remember the size but Rocky Road can tell ya, i ended up calling them to find out. I got a good expensive metal fancy bit and it was so worth it. Made drilling holes while lying in grease and dirt so much nicer. It came with self tapping bolts for the frame so the hole you'll drill is smaller than the bolt, I wanna say 3/8's but check before obviously. I did mine this last spring so details are slipping away.

I had two of us hold the slider in place while the third guy marked all the holes to drill. Another reason to have friends there to help hold.
