Thanks John, I can see things will change for the better with the new members.
The lever was the whole problem to getting the gate right. The holes were drilled at opposing corners. A number two screw was used to attach the lever to the gate. The length is 1 7/8th , the width is 7/16th. The lower hole ( left) is 5/64th, the upper is 3/32nds. The rod is 1/16th for the gate.
The lower lever was the second one made ,the picture is outdated from the dimensions given. The right hole was drilled out from 5/65ths.
The setup was changed, the lever was placed on the outside.
The block spacer is 1/8th of an inch thick and keeps the hook at the frame in place with the lever.
I got lucky on the second try. I rushed this one but I know it works now. They are neat little dump cars. Ebay had a few without gates. Oh yeah the logs are 5/16ths diameter and 5 inches long. I used 8 of them.
