I looked around and compared. Terry McIntosh had the best looking best built arms for a small stretch in my opinion. Lots of opinions out there however.
Here are a couple of pictures of mine to give you an idea. They are not cheap and not easy to find unless Terry is building them again.
And Devil Dog is very wrong about noticing a difference!
Well depends on what he is talking about... Looks wise, most can't tell by glancing at it if it is 2-3 over. That was one of the reasons I didn't want to go longer. I can tell a big difference in mine as far as wheelie control. Even when set about 2.25" over.
