LMC Tach for 1987 Model?
 

I have been looking at the LMC Tach for some time, would love to have that factory looking tach in my dash. I have read some of the write ups on here about installing one into a cluster and how to relocate the fuel gauge.

One big mystery I have stumbled into is if this will even work on my truck - I have a 1987 model with EFI. I have read somewhere that this model year cannot have a tach, because 87 EFI trucks have speed sensor (VSS) feedback needed for the factory EFI computer.

I wouldnt think the VSS would be affected by the tach, but i have never tore into a cluster before so maybe its on a spot where it wont work?

If anyone has done this on an 87' model, I would appreciate input. Thanks!

My '87 TBI truck came from the factory with the tach cluster.

Not sure on your specific model but I converted my 89 CC dually w/TBI to a tach dash & relocated the fuel gauge over to the blank spot w/the smaller gauges.

Sounds like its a non-issue then - SCOTI - did you cut a hole in your stock cluster and run wires over to the new fuel gauge spot like I have seen some do - reusing the stock printed board? Or did you handle it differently?

Re: LMC Tach for 1987 Model?
 

Yes, yes, & re-used the original printed circuit board.

I used the LMC small fuel gauge & a 7k tach w/both using the later year models font so everything matched the remaining OE gauges.

I like the look of that 7k tach - where did you get it at? - the LMC ones are all 5k tachs.

How difficult would you say this install is? I know its always a pain to take the dash apart for me - seems like it takes a good amount of time to get it all out and then back together for me.

Mattchu60, I'll be watching this. Please post the success you have. I have a 91 cluster for my LS conversion and would like a tach and relocate the fuel gauge as well. Good Luck, Mike.

Be advised though, they sent the tach & the 4 gauge cluster assembly. But, the font style for the 2 upper gauges were 81-87 while the lower 2 were 73-80. I was kind of pissed about that. So I ordered the correct font fuel gauge & did it that way. That 4-cluster set-up is still sitting in the box on a shelf.

Ok - I have seen these before - I don't really like that you have to order the new tach along with the 4 gauges as one unit, but i suppose it is convenient for some to do it that way vs buying a stand alone fuel gauge.

The 4 gauge pod seems to have the correct lettering in the picture for the bottom ones - but something does look "off" about the lettering, almost like its too small or something. maybe it would look fine once installed.

Here's what the factory setup looks like (in terms of font) -

Does anyone sell a kit that allows this upgrade to a non tach cluster?

Re: LMC Tach for 1987 Model?
 

Brothers or LMC are the only ones I've seen. I know LMC has them listed as a back-ordered item.

Pretty pricey....:)

Agreed.

Usa1 parts has the same set up as well.

I am building my own as well.

Early mock up stages..

Sorry I waited on purchasing a 7K tach, Looks likes the new ones are gone forever.
