I need help/ assistance mounting a skid

[Vector LTX GT 08]

I am currently building my 2007 attack. I am replacing the 136” mono with a 151” 2017 (700 mile) venture suspension ( pivoting rear rails). I am building a different sled as Yamaha has never done something in between on an Apex. It’s either 144 or 162”. I am putting 8t wahl drivers into it also, so I am replacing the 9t OEM drivers. I drilled/ removed the front mounting brackets (136” mono brackets ( they will work with the 151” suspension, just have to be moved/ re riveted). I have the factory 9t drivers still in the sled as I want to get it mounted first with the 9t as I can always go back to 9t drivers if I don’t like the 8t. It’s not letting me post pictures off my i phone 8 to the post.

The front of the suspension isn’t contacting the cement floor as the front mount holes are in the factory 136” holes. It appears the mounting hole needs to be lowered/ moved back 1/4-1/2”.
