I've also got the unilite on my vert. I did have some issues with cross talk from a spark plug wire, but once I got the cable routing cleaned up I've not had any more issues.
I've got a silicone (I think) holder I bought from one of the 3 auto parts chains.
I use it on my dash, phone upright horizontal for GPS and forward camera. Phone laying flat for HUD. Laying on front slope of the center console for "normal" use.
When I bought my Lars pump, it came with a bolt, washer and nut. Press on. Having said that, I instead used a installer/removal tool from Orielley, but in effect did the same press on function.
Yeah the pulley on my L code was put on backwards. I'm going to have to use a press and some plates to remove it and try not to destroy the two. (On the right)
