I've got a 1984 pajero, but it doesn't have any
original rims (all four are different sizes) and for
the life of me I can't figure out what the right rim
size is.... Any help would be awesome, it's my first
car and I want her as original as possible
(exactly the same as pictured, colour and all)
It's most likely to old to find any OEM wheels, you could try a wrecking yard. But if I remember those from back the wheels were not very substantial. I would try a good tire/wheel store should be able to come up with something more substantial and look fairly close to the OEM look but maybe made out of an alloy material.
