what is original, what is rare option, what is not?

you need to find the build sheet to know for sure and it should be under the rear seat tucked in the springs if someone hasn't already removed it, I would say that is all after market installed, the light guards and fog lights were 70's and early eighties aftermarket products, the police wheels are added after, as far as I remember they were only available on police and b-vans used them as well but the B-van ones wouldn't except the dog dish caps as they didn't have the nubs to click on, instead they used center caps like ralley's, also that push par is police to but added after I am sure, nice ride though
