with the shim that thick does the locating pin for the housing need anything?a longer bolt to reach the axle perch or something?




Not in most cases IMO. I have seen some different height locating pins, but most IMO would be plenty long enough for a 4* shim 3/8 thick on the fat side. As its thickness would be half that at the pin.

But it would be something to check.

But, I say, Go ahead with the 2x4 mike
