6 cylinder tach

[muleys67]

Hello all. I recently was lucky enough to buy a 72 chevy tach dash along with a gmc fiberglass console, both for $50. Yes,$50. Okay,yeah,well the dash isnt perfect by any means, the bezel is not usable and the circuit board is
trash I think. The pcb is separating and a couple of circuits are broken.
I want to install this dash into my 67 truck so I have a bezel. My question is this, my truck has a 292 inline engine. Can this tach be reworked to run on my engine? Truck has a 4:11 rear gear and a 3 speed trans so a tach would
ideal. My computer will not let me run a program for the digi cam we have so no pics,yet. Im sure the tach is from a V8 truck. Thanks for any advice to
my questions.
Oh, yeah, the console is in remarkably good shape.Could use a good cleaning,
maybe a coat of paint. One bolt hole is broken but bad at all, a large washer can fix that. Again thanks for any help. Muley
