That empty bezel bugs me. Is there an aftermarket tach I can get to stick
in there? I note that LMC truck's catalogue lists fuel gauge w/tach or w/o
tach, whatever that means. The illustration just shows a fuel guage. My
instrument cluster is the two big guages for fuel and speedo, plus the four
small, three of which are oil pressure, volts, and temp.
I put a small 2" tach in my '87 Pickup... where the brake light is. That
would be your fourth place on the dash. Takes a fair bit of dremmel work
There has been some discussion and pics here...
How much "older" are we talking here? I have an '86 Blazer that I
added a tach to. If you have the HEI distributor, there's a tach feed
on the cap right next to where the 12vdc "hot" wire comes in on the
The non-tach Chevys used a large gas gauge, next to the speedometer.
It's the same size as a speedometer or tach would be. There's also a
blocked-off, unused dash opening on the left (bottom left) next to the
temp, volts, and oil pressure gauges on mine. I don't know if you have
a similar year as mine, so your parking brake light may be there. On
trucks similar to mine, the factory tach would be where the fuel gauge
is, and a smaller, "non-tach" fuel gauge (as you mentioned) would be in
that empty space.
You can swap the entire instrument assembly from another truck. They
go for like $20-$30 for the non-tach version on eBay. But the versions
equipped with a factory tach often go for $125 or more, so the
aftermarket tach is the cheapest and easiest way to go. Adding a
factory tach-equipped instrument panel may be more involved than just
plugging it in. I added a cheapo, $35 tach from Pep Boys onto my
steering column using a large (4" I think) hose clamp. Only problem
is, it moves with the shifter, so I set it to be out of the way and
level when the truck is in OD.
Hope that helps.
