I like that idea, I was Just thinking about doing this today after you mentioned it begore
It's super simple, just remove the screw and nut, keep the stretchy Velcro, remove yellow pad from clamp(slides off) put screw through frame and pad. I realized in the field that I needed to reinforce the pad since it's bigger than the frame that supports it so it wanted to roll back with pressure, I had some brazing rod handy so I cut it to stick out a little lower than the pad and zip tied it to the frame, it's lasted a year now so I'm just leaving it like that.
Well I just picked up my first set of digital gauges. I have the hilmor brand with clamps and hoses. I read some reviews here after I got them. I guess time will tell, haven't got the chance to use them yet as it has been raining here for ever. I will say that I feel like I got a good deal on them $485 plus tax. Clamps and hoses included. I will be getting the case as well digital or not I like to keep my tools protected.
