Thank you! So you wouldn't mind pulling yours off and grabbing a fish scale to compare the two would you? lol...just kidding.

Yeah, I had read that description on their website but didn't know what 'instant center' was. But I also stared at those two pictures for 25 minutes and never noticed the difference, lol.

It makes sense (from what I have read) that the two piece driveshaft version would have the flat lower tube and that base plate to rest on the ground.

What exactly is instant center? I'm assuming it has something to do with the pinion angle from your post?

Thank you, Sir!

No apologizes necessary, It was good information. I would have opened the trac-bar box and immediately started a new thread about those holes, ha.
