[Kart54]

I happened to catch this thread and later on that evening a special on the top 20 drivers of all time on ESPN. Without commenting on their choice of drivers, (I do think they blew it by not including Mark Donahue). I couldn't help but notice that this cage is identical in roof design, corner attachments at the roof and laterals at the main hoop to one used by Richard Petty in the mid 70's. The shot inside Petty's car was very clear and his cage matches this one to a "T". Its also similar to a short track cage used for Saugus Raceway built for Ron Hornaday Jr. by Speedway engineering of Canyon Country, CA in the early 80's.
I guess it just goes to show that everything old becomes new again.
I don't know the guys designing this cage but if you can you might want to access the design for Petty's cage in the mid 70's or contact speedway engineering (They currently build NASCAR truck and Winston West set ups) Yours is a twin to both of these earlier designs.
