What disk brake upgrade for a 74 duster, not Wilwood

yeah but then the car in front of the cop, doesn't match the recorded modifications so it invalidates your insurance and roadworthy test if needed in that state

i.e they throw 2/3rds of the book at you

the last 1/3rd would be no licence

gets expensive and you'd probably be getting the bus from then on... at least for a while.

some states will tow and impound and may move to destroy an illegal car depending on what you did to be in front of the cops/court in the first place.

they don't mess about
