Duster Roll Bar on Ebay?

Are you talking Roll Bars or Roll cages...?

Never seen a 10 pt roll bar....roll cage yes...

roll bars are 1 3/4 tubing....minimum thickness of tubing is .118....but due to variations in tubing...you need to buy .134 tubing to ensure you got the correct thickness....

Before investing in buying or installing a roll bar or cage i would recommend you buy a rule book from the sanctioning body where you are going to be racing.
