Gen Swap Swingarm

[13013]

So I've got a bead on a 0-6" trac dynamics extended arm but it's for a gen 1. I've seen where the difference includes brake location, and dog bone bushing. Anything else?
Has anyone swapped these?
Is it a huge hassle?

The one I'm looking at is well under half price of new. And is in pristine shape itself. I'd like to go 4" over at some point. And this deal just came up. But if it's a hassle I'll probably pass.

Sounds about right. Rear brake and the lower pivot sleeve are the only differences between the two arms.
