Descriptions of both show them to be compatable with a Dyna. I have a 2006 Street Bob on which I installed the second one you listed. It is adjustable to two different positions...high or low.
The ones that adj. are better. You can actually turn them up side down from side to side and get four adjustments for distance. I run mine upside down on the farthest setting and its perfect for me.
Buy some forwards and call it a day. No worries about moving feet back and forth,they look better (and cleaner) and they aren't but like 100 bucks more.
