My tach install thread
Well, i finally decided i wanted a tach in my "gauges" cluster. So i did some quick research and decided on the Sunpro FZ88R. It has a similiar look and correct sweep. As far as i can tell its only availible in the 3 3/8" inch size. I ordered it from Summit Racing at the cost of 129.99. It comes with a mounting cup and 2 brackets. Steering column mount and dash mount. And screws and instrucions obviously. No wires.
I have some pictures here that illustrate how it fits in my cluster. This tach is a sealed unit. Which means you cant take the internals out unless you cut the case. So im going to attempt to install it as its comes out of the box. Initially, it appears to fit very close. So i am going try to design a plate to go over the back of the cluster housing to bolt the tach to. So this is as far as ive gotten. I plan to finish this in 2 weeks(dont hold you breath..lol). I will try to get my plate cut out and finished within the next few days. More pics to follow soon. Any questions? |

Re: My tach install thread
In the last picture you can see some of the chrome face exposed. I will try to paint the face black to eliminate the shiny spots. The face is offset a little bit. So opening up the black cover plate to a full circle may not work. Oh, and i did have to file down the back of the black cover plate because it had a radiused protrusion sticking out. But i didnt have to file it flush. I will try to get a picture of this, but i have to take another cluster apart to get the picture.

Re: My tach install thread
Very interesting, look forward to your progress. Do you plan on installing anything in the other left hand hole?
I plan on starting my conversion soon, but have already purchased a reproduction tach from one of the old Chevy parts houses. Debated a long time on what to do with the other hole as long as I had the cluster out. Thought about a vacuum gauge, clock, etc., but finally decided on a Volt Meter. Just awaiting for it's arrival before the fun begins. I ordered a "Auto Meter 2319 Auto Gage 2-5/8" 10-16 Volt Short Sweep" Hope I can get it to fit, and look decent. Good luck on your project. |

Re: My tach install thread
I have been considering this EXACT SAME mod!!! Man, I am definitely tuning in to this thread.
My ideas were similar to yours, but I was planning to disassemble the gauge, which meant gently prying open the crimp on the chrome bezel. If you did this, you might be able to utilize the factory gauge plates. Looking at your set-up, I might just do the way you're doing it, as it looks much easier than my way. I was going to contact one of the gauge overlay companies and see if they would make me an overlay with the correct green lettering to match the rest of the cluster. I found overlays for 5,000 rpm and 6,500 rpm faces, but nothing to match the new Sun tach's 8,000 rpm sweep. If you're looking for a cheap idea to fill the left side of the cluster, check out my '64 build thread and see how I did my vacuum gauge for cheap.

Re: My tach install thread
It’s a shame they didn’t produce this new tach with the same bolt-together technology found on the vintage models. It would make things a lot easier for gear heads that can’t leave anything alone. I have had good luck in the past twisting bezels off gauges and using the guts inside factory panels on 1940’s cars. Just a little scary on a brand new gauge costing over $100, since you can’t know for sure what else they may have changed until after it’s torn apart.
Looking forward to seeing this all back together. |

Re: My tach install thread
Lmc list a tach conversion kit on page 73 of the catalog. Said it's for trucks that didn't come with the tach in the factory cluster.

The casual observer would never know that didn't come from the factory.

Re: My tach install thread
Thanks for the kind words. I still have to finish the back plate for the tach to bolt to. And i also am going to track down a clock for the other side. If i can, i plan to make these back plates to sell. Got to finish the design first. I found the tach through summit racing, but saw it also on ebay for 99.99. I paid 129.99. I wanted to go through summit in case i had to return it. I will try to get pics of the way it came out of the box. I considered just putting on my steering column. Then decided to put it in the cluster.

Re: My tach install thread
I was looking at the exact same tach for my '65. Can you give any details on the bracket you made?

Re: My tach install thread
Not sure what details you would like. Im not finished with it yet. The gauge is just sitting in the hole temporarily. I tried something different today and it didnt work. Im still trying to come up with a way to bolt it. Time is kinda short with the holiday an all. I will try to work on it tommorrow again. I will give an update soon.

Re: My tach install thread
Heres a picture of the black overlay plate. It has a raised part that needs to be filed down. In my picture you can see this, right at the end of my marker. I just filed it down flat. Otherwise it holds the tach away from the window to far.

Re: My tach install thread
Heres a pic of my plate almost done.Im gonna paint it yet. Its 2 pcs of aluminum welded together. I have some other ideas about making them from steel. Once i get back to work after the new year, i will have access to a plasma cutter and will try to make these from steel.

Re: My tach install thread
Nice work!
I just replaced the backs on mine for both the clock (custom) and used a tach similar to that, but not as nice. ![]()

Re: My tach install thread
Thanks for the compliments. As far as selling them, i have a few other design ideas. I wont be able to explore them till next week or so, when i go back to work. Im going to try to make them out of steel instead of aluminum. The real problem is cost(isnt it always) and time to make. I should have bought the tach that classic parts or lmc has. If could source the tach for under 100 and get the plate for like 40, thats closer to what i think people would pay.We will see.

Re: My tach install thread
I have been keeping trac of this from the first day. By far the best post concerning tach alternatives. I have an original Sun Tach but it is for a V8 and I will be keeping my in-line 6. The original tach is engine specific and to have it refurbished at about $260 is cost prohibitive. Your Idea is perfect. Now for the question. Have you looked at removing the chrome bezel prior to mounting it? And what would be the pros and cons in doing so?
