A Q for Charles:
I want to do this retrofit fairly soon. There is one highly regarded local P-car specialist in town whom I'd like to perform this for me (here in Victoria BC Canada). They are called Forward Automotive. Are you aware if this garage has performed this retrofit yet? I'd like to know so I can be prepared to explain the retrofit to them if they have not.
