Go for the '68 Firebird (that would be for six or eight cylinder) look (design yours for a four cylinder tach you have already bought that is a size you can find another like model, were the first to die). This must be a weather proof model, since it would be in the hood "bump". And of course can be set for 4, 6, 8 cylinder.
Disassembling a new one to set the odometer looking easier? Were looks to count for anything.
