I love finding those original speed parts. I have a Sunpro tach built in 1969. It has a cracked lens and unfortunately Sunpro doesn't sell spare parts to replace it. I guess I will have to find some clear plastic to do it myself. Like everyone else said, lets see some pictures!
Older tachs often don't have the intenal circuitry made to work with modern electronics. I put my old Mallory tach on the Austin with my Pertronix distributor and it wouldn't work. It spun the needle in 360 degree circles. Had to pull it and put a modern Sunpro in the car. The Autometer I originally had in the Austin worked perfect, but too new looking to use in the car.
There is a company that rebuilds the older tachs to todays standards here in Seattle area. I see him at the local swap meets and drag reunion shows. If you are interested I can get his card out and send you his contact info. It is a bit spendy though.
Geerbang, that is what I am going to have to do. I was hoping they had replacement lenses. I was thinking it might be a few bucks if they had one. Now I need to get some tools to cut it, which isn't a bad thing! New tools are great.
Very cool indeed! We had a local Moon rep who had a bunch of new tachs repainted in that pattern 5-6 yrs. ago, and quickly sold them all quickly. I never heard about it until my buddy got one, and I called to try and buy one, but too late.
Well now I need to find a reputable repairman for this tach. Hooked it up yesterday and the only thing that would work was the light. So I dissected the tach and the needle has come detached. My hands shake to bad to perform surgery on this gem so it's off to a repair shop. You guys have any reputable places in mind ?
I did find a date of April 1972 stamped inside the tach. I was giggling when I found that because the tach is a year younger than me. Hahahahahahahahaha
We have a local shop called Instrument Sales and Service. They been around for at least 40 yrs., and have an excellent rep. If it's just putting the needle back on you should be able to find any instrument repair shop local to you that could reinstall the needle.
