I've got a executive model u12 pintara, and just pillar mounted a 3 3/4 inch tacho it looks sick and was so easy. I also have a vacume/boost guage, that was'nt so easy, just left of the instrument dash there is a little rectangle piece of plastic with a nissan logo on it, I had to take that out, attack the dash with a file to fit the guage in, then mounted the guage in a seperate piece of plastic to cover up the dirty great hole in the dash. looks good now that it is finished, I'll get some pics as soon as possible.
