73-80 and 81-87 interior compatibility
I have a 76 k15 GMC and an 81 c10. I recently bought most of the interior from another 81. Some of the stuff is for my 81 but I would like to use the guage cluster and some other items in the 76. 81-87 guages look and work so much better.
I did a trial fit on the guage bezel and it is so close to fitting it's not funny. Now that I have seen it in there I gotta have it. If I use the cluster from the 81 will everything fit together properly? I know the best answer is go ahead and try it, but maybe someone can save me some trouble if it doesn't work. All of the guages are in the same place except mine has a brake light and the 81 has a clock. I have the guages, circuit board and trim panel. Is it a direct swap? Thanks everyone |

Re: 73-80 and 81-87 interior compatibility
i belive there is differences in the wiring harness but the dash construction is basically the same

Re: 73-80 and 81-87 interior compatibility
You'll need to use the newer dash pad with the newer bezel, they are shaped differently. That said, there are significant wiring differences between your 76 and the newer instrument cluster, expect to be totally re-pinning your instrument cluster connector, and also having to run a wire for the newer electric oil pressure gauge vs your original mechanical oil pressure gauge. Pay special attention to how you wire the volt meter that will be replacing the amp gauge, if you simply plug a volt meter in without re-wiring it properly (to be in parallel instead of series), you will start an electrical fire.

Re: 73-80 and 81-87 interior compatibility
OK, I really want to keep my early dash pad so I'm just gonna keep it as is. And I'm not really interested in a dash rewire. I have bigger fish to fry right now.
Thanks guys Last edited by xbanone; 06-20-2009 at 11:46 PM. |

Re: 73-80 and 81-87 interior compatibility
Your better off looking for a 76 cluster that has the gauges you want. A good clean up and fresh paint on the needles along with a new bezel goes a long way....

Re: 73-80 and 81-87 interior compatibility
Yeah, a good clean up and some paint, plus painting the rear white will go along way. The biggest thing is the trim bezel, mine is black and cracked and the newer one is silver and looks much nicer. I'm gonna try and make it work.
