tach and oil psi gauge?

In my humble opinion.....
Any of the classic style Stewart Warners, the redline Power series, the green lines, or the deluxe guages (the deluxe look like they could be from the fifties)
If you REALLY want a time warp tach..... a SW or Jones Motrola/moroso mechanical tach. You'd need a drive cable and a tach drive distributor.
I think a power series SW is probably a better choice. Burgundy, titanium orblue/gray stripes on the face.
