i pulled a swabar off of this camaro some guy tore down the other day and i measyred it it looks to be a 1 7/16 or 1 3/8, bar what model did these come off of?

its probably a 36mm bar. Probably an iroc, maybe a bird

thats what it looks to be. what size is the 1le bar?

36mm was the biggest stock bar you could get and they were on irocs and birds but not all of them. anything bigger then the 36mm would be aftermarket and made by hitchkis....mine is 1 7/16 and JUST fits. anything bigger and it would hit the pitman arm.lol
