Right on- I have metalcloak fenders and I think it might be easier to modify tower instead of lower shock mount. Plenty of room- I only need to get 1.5 to two inches more on my current 11 inch travel bilstein resi's to be happy. Currently have 3.75 up travel- barely enough around town!
I want to keep my stem uppers so I am looking at ford f250 tower and instead of tabs, trim the top and add a 1/4 plate across, drill a hole and bolt her up. More metal on shock tower to tie into anyways.
