How much trouble is it to replace the warning lights in a 70 with factory guages? Are the guages available and where is the best place to get them. What about the tach and what tach is correct for a 70 SS 396? Thanks

How much trouble is it to replace the warning lights in a 70 with factory guages? Depends on what kind of warning lights you have now. If you have the round warning lights, it will be a little easier and cheaper. If you have the sweep dash, then that needs to be replaced too. Do a search under username "Steve S" he has done several and helped many others.

What Hp engine? The standard 396 got a 5500 redline.
