Weld-in roll cage kit (1.75 x .095 DOM) Was spec'd for a 1988 Mazda 626 but should fit similar sized vehicles. The vertical tubes are over length so they can be trimmed to fit.

Main hoop dimensions:
55" across main hoop at widest point (vertical tubes are straight up. They only looked splayed in the picture)
15" from widest point to top
43" width at highest point before hoop radius at top (approx 2" from top)
45-1/2" overall height
Halo dimensions:
39" across (door to door)
20-1/2" front to back
Rear down bars:
59-1/2"
door bars:
39-1/2" between main hoop and front uprights. I couldn't think of a good way to measure the upright profile, so I attached a photo of one of them up against a 2003 Sentra that is in my shop. For reference, it looks like the cage could fit in the Sentra with a bit of trimming.
Main uprights width:
55" with dash bar between them
footwell braces:
17"

Kit includes the backing plates and gussets. Not sure what the 4 small tubes are for, probably additional bracing? Cup holders?? Window net?
