70 442, I’m replacing my front sway bar because mine is a bit pitted. I bought one from Fusick and it is 1-1/8”? I thought I’d try it out it its a little too thick and rubs idler arm. Does anyone sell the exact replacement?

 

Oldsparts.com has one they refer to as "Factory"...

Parts place sells a 1-1/16 front bar - have it on my '72 and it clears everything

1972 Oldsmobile Cutlass/442/F85 FRONT SWAY BAR - 1 1/16" | Oldsmobile Cutlass/442/F85 Parts | SU5596A (thepartsplaceinc.com)

 

These cars can accommodate 1.5" front bars. The problem is the length of the link used to connect the bar to the lower control arm. Some installations require the use of the F-body end links.
