Thanks, thats what i was thinking but needing some confirmation here
in order to get weight on it i will have to bolt the everything together..the axel to the springs with the "loose" perch underneath and check angle from there. unless there is another way to get weight on it, thats the direction i plan on going. i also have 2 and 2.5 degree shims but since im welding the perchs i think i can avoid that by getting it right the first time with perch
