I just saw you were in the Joe's file, didn't catch that at first. Finally got back here to add some scans from my book. There were a couple diff tillers shown. Think yours is going to be the Fig 4-1.2 here, you have the right mounts on frame. The Fig 4-1.3 is older style without those frame mounts. Seems you will need in back the two strap lifts, which you might make, #;s 20 and 21. In front, much more missing, the most important parts really. Two side straps #4 slip over back bar and up to the front mount to hold it back in place. The whole rockshaft #7 is needed to mount and link the tiller to the spring assist. Then there is the Locks that are pinned over the bar and into the mount hole above to keep in place. The 45 spring assembly for tension. Think one could get away w/out that spring and still work, but maybe that is for belt tension now that I look and you will still need it. Here's some scans, hope they show enough.
