Old or new gauge cluster

[Hhan's 57]

I am about finished with installing a heidt's IFS, power steering, and a new 700R4 transmission. I have also installed a new flaming river steering column and will soon have a 70 El Camino 12 bolt 3:73 Posi rear end to install. Now I am thinking about the guages, since they have never really worked. Now I am trying to decide if I want to rebuild the old guages or go with a new set. What do you all think? I would like to see some photos of some gauges to get some ideas. Any type that works well and not to hard to install? Here is what's completed so far..
