frame of crown is same in all the old models till 93 or 95
so to change body no alteration is required and this is a news to know that if there is any duty in Quetta only and no where else i hope Queta is still in pakistan lol
let me ask if u modify ur civic totally and change it all the doors fenders tyres and engine and seats etc etc will it make it illegal , no!!!same is the case in crown u are just changing engine , doors , bonut ,diggi , seats , roof , and tyres so any of change out of these things in any car is illegal or what
so that the point which make the changes in crown legal
and i think to be more careful u can also have advise of some custom agent
