Chris sent me 11mm shims, which he is pretty sure are the standard ford size, but also sent 14mm shims just incase.

Hmm crap I went to ford last night and ordered them... I can’t remember what size they were.
Since there was 3 different sizes on their computer system, but only one marked as “standardâ€￾. Hopefully they come in today and I will grab the size and part number.
Oh and as far as I can tell according to the ford part list on the computer they cost $3.25 (which could be wholesale, what they pay etc... nfi but yea )
