    Center Cap Dimensions

    Awesome! Thanks for the measurement. I don't think drilling holes in the rims will work since the bolt would hit the hub, I guess it depends how thick the rim is. I'm thinking I'll have to grind out that raised plastic on the backside of the center cap and then Tig weld a nut to the face of...

    Center Cap Dimensions

    Does anyone know the diameter of the 4x4 rally center cap base? I'm hoping to mount them on a set of el-cheapo Rough Country steel rims but I'd like to know if they'll fit in the wheel before I spend $100 on a set of those center caps.

    Mystery Tachometer

    I finally got some time today to re-install the gauge cluster and wouldn't you know...problems. The tach didn't work, the temp gauge pegged out when I turned the lights on, and all the gauge needles would bounce with the blinkers. After a couple hours of electrical diagnosis I found that the...

    Mystery Tachometer

    Got my cluster out tonight, that gauge is definitely a custom job as you can tell by the pictures but it's actually not too bad of a job. I hooked it up to my power supply through the circuit board and the tach snaps to zero. I'm not sure why it didn't work in the truck since the power and...

    Mystery Tachometer

    This is good to hear. My 6AL does have a tach output. Back in the day I used to have a 1988 K5 blazer with a MSD street fire box and a summit racing brand tach, the tach signal was super lazy and inaccurate, I also tried a sunpro tach but had the same problem. I figured I needed the MSD tach...

    Mystery Tachometer

    Yeah, this doesn't surprise me. The whole truck is Frankensteind together by the previous owner, now I'm doing my best to un-Frankenstein it. Hopefully I can pull the cluster this weekend and find out how that tach hooks up; however, I'm doubting it will play nice with my MSD 6AL box, but I...

    Mystery Tachometer

    Well dang, I never even thought to look at the bigger trucks but a quick Google search confirms it. The fuel gauge works and is pretty accurate so hopefully the tach works too. I'll have to pull the cluster and see if I can get it wired up. It would be really cool to get the whole factory...

    Mystery Tachometer

    Hi everyone, after a ridiculous amount of online research and coming up with absolutely nothing I decided to join a forum and hope that someone else has seen this gauge before. So I'm in the process of "restoring" my 1986 Chevy K10 Scottsdale, after 8 long years I've finally found the time to...
