So I wanted some space to mount more gauges and my altimeter was broken. What to do.... Below is the answer I came up with. I welded a frame onto the stock altimeter mount, and I think I will be able to mount three gauges on it quite nicely. I still need to make a bezel of some sort, and install a few more gauges too. but for now, at least I have a boost gauge. Sorry about the glare in the installed pic, I will take a new one someday.
