All excellent suggestions, thanks! It seemed like the suggestion of mounting the engine first THEN attaching the needle would work with the least fuss, so I tried that first. I spent a while wrestling with it (it's still quite a tight fit in a very limited space in there) before one of the nuts fell out of the bottom of the mount. Rather than stomp the poor thing I'm going to go to bed now and drop by the LHS in search of a Dave Brown mount tomorrow after work.

Looking over at my Avistar, it has the same mount. The OS .40 LA fit much easier there than the .46 AX does here!
