shipping OS is shipping. i dont think the destination matters much. only the setup of his jig to make 5+ at once is worth his while.
anyway, Rhys if you dont mind looking into it, i believe you have 2 people already!
there are plenty of M35s on the forum also.
do you mind taking a picture of the outside of the car with the bumper on please, post-install?
and does your M35 have a standard rear bar or an Aero bar etc??
