finally got done moving the top box back 2 inches on the csc trike. i used 1 inch by 2 inch by 13 inches aluminum bar.
took the dimensions to my local metal fab place and told them what i was doing. took them a day to get them done.
i painted them and installed them, making sure i put permatex around the bolts so the lower trunk doesn't leak. it came out ok but is very noticable. or maybe its just me because i know its been done and the trunk used to sit nicely in the surrounded area. heres some pics.
