Want to put and aftermarket tach in a rallye dash

Anybody here put an aftermarket tach in a rallye dash where the blanked off center hole is. I am concidering doing this in my sons rallye dash. I am keeping a vac gage in my rallye dash and using a shift light. I have seen the $240 aftermarket rallye dash tachs and heard they are junk.

What aftermarket tach did you use, and how did you mount it? I was concidering making a flat aluminum plate that screws in where the tach mounts, and drilling out its center to mount the gage into to it. I am looking for ideas, and pix with different tachometers used in this location.

Thanks
Matt
Redline installed for me works great!These aftermarket tachs don't seem to work good with points,Mine works great with electronic Ing.
