I think you would be better off ditching the coil spacers and buying a 7" kit. once you get up that high you need things like the TC indexing ring. If you're planning on buying a kit anyway you might as well buy one that will supply you with all the necessary parts to give you proper front-end geometry.

 

i hope you have deep pockets if you do decide to go with the 7" skyjcaker kit, not that the kit isnt worth it but it is expensive.
