Zach...
Presonally, I wouldn't put it on the column.
When I had my transmission done by Fred at Desert Diesel, he had an SPA gauge on his column, and I just didn't like it a bit. You can't see most of your warning (dumby) lights. Trust me on this, it gets old having to look around something to see those lights (especially your overdrive off light), as I had to for 6 months when my steering wheel was turned 90* right.
Wait till Friday and take a good look at my gauge mount in the cubby hole... you definitely don't have to go with the mechanical boost gauge (although it's a good, easy to install, and cheap option, and has worked well for both me and Denis now (knock on wood)). With the FP gauge, you don't need to look at it constantly (especially with your PE4200 pump) so you don't need it right in front of you.
Just my thoughts, and I know others will differ, especially about viewing the dumby lights, but that's just how I felt about it when I looked at Fred's.
