Finished cleanup, located weldment, looked at drawings to verify I was using the new hardware I bought in the right places. Inserted all the weldment to spar bolts, washers and tightened the locking nuts finger tight. It looks like most of the bolts are too short to extend through the lock nuts. Will try a few and measure more carefully tomorrow. I may need to order longer bolts. I got to use two tools I bought long ago and never needed until now. They both allow you to reach into narrow deep slots. One grips a washer the other grips a bolt or a nut. The one for the washer needed to be another 5 or 6 inches longer to really work for some of these washers. I also got a chance to use my Crescent brand long reach X2 needle nose pliers. They were easier to use than the tool that grips a nut. I'm going to try them on the washers tomorrow.
