How to get to this 'stance'

this is my 67 dart.




i have moved my springs in with relocation boxes and sliders. my boxes are drilled with the holes in the farthest upwards position possible. I have also converted to sliders in the rear and they are 1" notched into the rear frame rails. my car has the cal trac mono leafs with the -1" then stock springs. i have no lowering blocks and the rear tires are 325/45/17. they are 12" wide and 27" tall.






top notch job !!!

just wondering....why the hole cut in top of the boxes?. ....for clearance w/ the spring eye?....To do over would you just drop the top holes a red C-hair?
