I am trying to replace the original clock on a 51 Chev, but I need to know the exact measurements to know if this will fit. Currently the outside diameter of the housing is 3 1/8" but the inside diameter of the body is only 2 5/16". Will this fit?

Asked by: JerryS_51
Thank you for your question. The 3-1/8” tachometers fit into a 3-1/8” diameter hole. The OD on the bezel/trim ring is 3-3/8”.

Will this tach work with my pertronics ignition ?

Asked by: Benny
Thank you for your question. Yes, that tach should work with your ignition system but you may need the 9116 tach filter because sometimes this ignition has noise issues.

How much room do you need behind the dash for #1890 tach to clear?

Asked by: jagger
Thank you so much for contacting us. The case of the gauge extends back 1-9/16" from the back of the bezel. The mounting studs are 2-5/8", though those can certainly be trimmed back a bit of needed. You'll also want to consider a bit of space for the spade connectors on the back of the gauge to connect it to the vehicle. You can see the exact dimensions on figure D2 of our dimensions sheet here: Hope this helps!
