- 1/4” x 2” to extend front & back members as well as the bottom members under the J/P

- ?3/4” x 1 1/2” tube to further reinforce / stiffen the bottom members that J/ P sits on

- 1” Angle (“L”) to reinforce/stiffen front and back (when raised, they flexed a bit too much without these). ?Hard to see here, but the angle is welded to back of front here (you can see against the floor). Same done on the back

- 3/4” rod to replace the short one
