Medevak1,

Look on the plans, the bolt on option is right there and covered on page 5 on the manual. When you get you plans (if they are the original, not some redrawn something) look on the left side of the fuselage page. You will see parts for the top of the windshield with a slot in the rear. This is for the plywood tounge from the center rib. The rear of the wing is held down with 2 nylon bolts just in front of the trailing edge ( a block in placed to keep the bolts from crushing the wing) and screw into the 1/4" hold down in the fuselage. Personally, on this plane, I like the rubber band feature. It saves the wing and fuse from damage in rough landings (minor crashes). My "band" sticks are from 1/4' harswood dowel and i have not had a problem with this size dowel, even on a .60 powered Ugly Stick. I use rubber bands made from 2 # 64 bands looped together and use a minimum of 8 "bands", 4 each side. If the wing is popping during flight, land and add more bands. PM me if you can't find the parts. Good luck
