For those of us with half shafts up front, any thoughts on what the engagement depth looks like and how much one can safely shim out the LCAs? Figure that 8-9mm shim stack would net about -2.4 +/- which would also pull the shafts out 1/3". Depending on depth of engagement it's either a nit or an "oh sh*t" and I haven't found specs to determine which.
