x2 what nm just said
NO quick and dirty answer
NO easy answer
however if you have a mill it is not hard to drill&tap & install oversize studs offset a little
There are 7/6 tops with half inch bottoms you can offset more
u just barely clean the threads on one side
you can calculate the thread depth and do the math
more than that takes inserts
there are also rockers with a wide range of arm lengths
did I say I do not like small studs with any additional spring pressure over stock?
someone here measured a bunch at one time
