Sun Tach in 72 Scamp

I mount my Sun Tachs on the dash, on left side by the A pillar. I use "double sided 3-M body tape". Take the half circle mounting piece, and weld it to the flat bottom piece, that gives you a flat surface to mount on dash, clean, and paint it up nice, and install. No holes in dash, and can be removed, with body tools.
