6 point bolt in cage for a e30 with floor plates that can be welded in (ties into the rockers and formed for the floor). The rear half of the cage is fully welded ie: the rear down tubes were never bolt on design. It has a harness bar and diaganol in the main hoop. Fits very good with the headliner in place, tight fit to the sides of the car as well.
$600 obo Im in NY would like to avoid shipping but might be able to deliver it within reason or meet half way.

here is a picture of the front half/door bar
