On a 69 Cutlass/442 did the FE2 and F41 suspension packages use the same front sway bar?

 

Per the Jan 1972 parts book, in 1969 the standard Cutlass front bar was 15/16". 442, HD, and rally suspension got 31/32". Vista Cruiser and police package got 1".

 

Hard to tell the difference when we’re talking 32nds. Heck a bit of rust could make it hard to distinguish. With basic caliper they seem the same.
Any other way to tell the difference? Both have rounded ends and have a bump on the end of the passenger side. One is on an original 442 and the other on a cutlass convertible. But the Cutlass didn’t have the rear sway bar.

 

The diagram of the different ends is in the front suspension chapter of your Chassis Service Manual. A single rounded bump is 15/16". Two squared off bumps is 31/32". One squared off bump is 1".
