In a 3 point I think the old Lakewood wont be accepted in NHRA. Some non sanctioned races will be fine with them, but usually it's on cars that run slower speeds not requiring a rollbar at all anyway.
I think they're cool, and whether they met tech or not they will add another level of safety to a street gasser, or any car that the owner wants something cool looking. I built 4 point rollbars for my Camaro and my Austin, jut for the little extra strength, and the look I wanted. Raced the Camaro for 16 years with my home built rollbar and never had any questions, but it never ran fast enough to fall into the range requiring a rollbar or rollcage.
