John, not sure where you mean to put lock nuts? The tapped holes in the aluminum slide end mounts of course are not drilled through as they come out flat against the steel tray.
I drilled through when I put in the wider spaced bolt holes as I don't have any bottom taps. I used lock washers and washers under the bolt head against the clamp portion of the 2" exhaust pipe clamp . Would have loved to have something else that the aluminum block to hold the grade 8 bolt.

Yeah Jim, I meant the side bolts that hold the engine mounting tray on. They need nylock nuts on the end but there's seldom room for a washer cos the hole is too close to the roof of the aluminium. The 4 studs could be redrilled to go through and have either nuts on the end or you can retap the existing to 8mm but I have been using 6mm Aussie 12.9 hardness steel studs with loctite threadlock. I notice the beijing stadium stayed upright last night thanks to our good grade iron ore.
