The lengths are the same center to center, but the hole in the center of the bushing may be different sizes. I thought there was only the small size or the large inner adjusting size but maybe not.
When I bring the car to work Monday (just installed awd drivetrain, 4/2pots, coilovers, etc) I will (hopefully) be able to drive it on the alignment rack and tighten everything and align it. I'm bringing some round type links and going to try and swap my taco type out. There seems to be three different hole sizes for the links though. There are two different smaller hole sizes with normal outer bushings and of course the type with the large hole where the toe adjusting bolt goes. I noticed the long bolt seemed to be more loose with one link I tried, both holes looked the same but were not. It was getting late so I didn't try swapping it. Monday I will hopefully have time because I have a short day.
