I plan to use one on my 63- 1/2T short bed. Vendors sell 1.125” diameter bars with down links to connect to the lower CA. I’m not thrilled with the appearance, but I do have one (yet to be installed).
Tonight I bought a factory 1T truck bar that is 1.25” diameter.
So my question is this, will I regret installing the thicker 1.25” bar from the 1T truck?

It's been quite some time since I spent my weekends campaigning an Austin-Healey 3000 in SCCA club races, but that's one way we would tinker with the handling for different road courses- - - -installing different diameter front and rear antiroll bars.. I have no idea how that kind of stuff would translate to how a pickup handles, but it will make a noticeable difference!

I imagine there would be some frame twist with severe cornering, but I drive like an old man, so the two bars combined should eliminate any major body roll.
