It is universal and should work fine.
Most likely as Pegasus is a Home Depot brand. Most drains' pop-ups are standard.
Most likely yes. These parts are generally made to a universal “oem” standard.
Sorry It is already installed. It looked a little bit bigger than the original one but it worked just fine.
All I can add is to adjust the angle of the rod. I had similar trouble until I changed the hole the end of the rod goes into the sink drain plate.
Thank you for your interest in Danco products. Our Danco 86783, 6 in. Lavatory Faucet Pop-Up Ball Rod, is not adjustable. You would not be able to change the position or location of the components on the ball rod.
No, it do not hold the stopper in place. Looks like it’s not the standard thread size. Not sure what to do yet.
No it doesn't.
Longer than the inside diameter of the drain pipe.
By default it was set correctly but you can push it in or loosen it to adjust the open close mechanism
