If you can't find any, you can go to Walmart and pick up a couple of cleats and drill them out for 1/4 inch bolts, the take some 1/4 carriage bolts and grind the edges so they will fit in the T-rail. You can also use green house bolts. They will fit the t-rail also. I've done this on my Excel and it works great. I was hoping I had a picture, but I can't find one.

There are also some pics on page 8. The better ones I think are there and also on page 5. No pics with the focus on them, but they are in the picture when I was taking pics of other things.
