I had a chrome moly 5 point bar installed in my old pump gas Duster, it ran10.00 a bunch of times and one 9.993 ET at 134.8 MPH at Woodburn, OR at the Mopar race several years ago. I was told at the time slip booth to not race the car again until it had a cage in it.
I discuss that with the main tech guy and told him I would make sure it wouldn't run that quick again, I knew how to slow it down by staging a tiny bit deeper.
The drivers side door bar curve down to the floor at the front of the stock bucket seat and wasn't a real pain to get in and out of the car like having it go to the floor by the emergency brake like I had on other cars
I did not have a rear seat in that car so the rear support bars hit the rear subframe on the top of the kick up on the rear sub frames
