| (sheet 2) Frame Modifications. Design instructions showing lightening holes in the thicker gauge frame have been completed. A design showing the frame cross bolted instead of welded to the side members has been completed, and we are working on designs for attaching the battery crossmember and 2nd crossmember to the frame sidemembers by means of bolts.
