was it always to wide.
was it in the game originally.
it looks to be from a moon patrol.
has it had any work done to the chassis.
theses chassis are famous for their width coils being seized up.
if you are careful you can use a hair dryer to slowly heat up the coil and it'd housing. yes a HAIR DRYER not a heat gun.
you will need the rite tool do not use anything else but a plastic tool.
you may need to change the width cap to get the results you want.
