Huh interesting I wonder if that bar was original. I have in fact talked to the old CEO of Bird from back in the day, Fred G. Schweser Jr. Nice guy, lots of cool info and resources on Bird karts, I just don't wanna bother him too much with questions.JT,
You were correct, my cart is a Bird Engineering Starbird.
After researching some, I found they were built in Nebraska by the company that built the Oscar Meyer Wienermobile. LOL
By the way, the bar you spotted on the back of mine is nothing but 2 PVC elbows and a length of pipe painted black LOL
