    Gents, found this vintage 6 cylinder Sun tach on EBay. Would like to find a steering column mount housing for it. Seems deeper than most of the housings I’ve seen. I’m hoping that a housing does exist for this model?
    Shows model RF-5 on tag rear of tach.
    Thanks!

    I can't help but doesn't it also say it is for a 2-cycle? Like for a 6-71 Diesel or a 2-cycle outboard marine engine?
    If that's the case it may read only half engine speed on a conventional automotie six cylinder.

    EDIT: I know most diesels don't have coil ignitions. They may have tach signal generators.

    Re the housing: If you want to get creative maybe part of a stainless steel water bottle or the like could be made to work. I once lost the stainless steel center cap for a motor home wheel and the RV manufacturer wanted $176 dollars for a new one. Nope. I sent my wife out for a stainless steel dog dish, cut it down and with a little hammer forming made it work. Saved $166 dollars.

    Additionally, the fact that it is an 8-grand tach would seem to suggest its for a 2-cycle six.

    Junkyard! Pretty sure it's a Camaro or Nova rally wheel cap.

    You could go back to eBay, I just looked and found a number of them. Search on 'sun tach cup'.

    I think the first thing I'd do is hook it up to an engine - any spark ignited engine - and see if it works. Depending on the number of cylinders and the needle movement you could see if it works and if it is relatively accurate.
    Doing this in a car with another tach wired in would be a plus.

    Maybe contact the instrument repair/upgrade places, see about converting it for your engine.

    Timcek,
    Just as an aside, if you insert a quote and then reply outside the OP's [/QUOTE] bracket your response will be displayed outside of the OP's message. Hope this helps.
