the passenger mount is on correctly, so no sweat there. like i said it looks upside down but isnt lol
that hole is probably e36 related, i just pretended that it wasn't there. s'long as you got the 4 bolts in your gravy.
by the way, i noticed you put the PS reservoir on the driver side mount arm...i think you should leave that open for a ground wire. i found 1 ground wire did not cut it for me, so i used 2 and it works great.
ps: what suspension are you running again?
