Buller jackshaft

We currently have a couple buller jackshaft setups, both have angled legs. I did a search but didn't have any luck. Do they have legs to make these flat?

Well, the common problem you run into is that the rear pulley is too large without being angled that on the Buller Jackshafts the rear pulley will hit the nerf bar post on a lot of setups. That's the only reason they're angled, if not they have to sit pretty high to clear.
