Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Infill plate to centre the rear number plate always looks good on those utes.
Never knew about that - I'm unsure how I feel about centering it haha!
I did more research into the plates and what the mechanic said checks out - if the valley plate is changed but the lifters aren't, they have 10-20PSI lower oil pressure issues. Just need to figure out how he saw the plate..
I was under the impression the sedan had DOD hardware and utes had the motors without.
