You must also be aware of the front roll cage bar angle. If the bar is less then 20* from vertical from the ground you will need to add support gussets. These are in addition to the roll cage gussets that are now required. My car currently has both. I checked out the SFI book on these chassis before getting miine NHRA certified. Brand new tag and a compliment from the inspector. He told me about 3 out of 4 side steer roadster had been failing for one reason or another. Check out my adds and make this car a nice new home!!!!
