Wondering if making small tabs attached to the old threaded studs is the best way to go? Would appreciate any suggestions or imput from fellow bolters who have done this install. | | | | | Joined: Apr 2009 Posts: 159 'Bolter | | 'Bolter Joined: Apr 2009 Posts: 159 | Someone else threw this idea out and it worked great for me: I cut the back out of my original gauges and installed th dolphin gauges into them. Then you use the original mounting tabs and bolts.

Then use the original mounting screws to attach the new gauges.

I suspect that is so they can sell us $130 bezel! By using the original housing, you avoid this cost and it looks like it was made for the truck.
