I see a extra standoff on the top one between the oil pressure and speedo

BTW, I am wondering why you are even considering changing clusters as they are identical as far as gauges offered?

That's because someone broke it off...

[hotrod24]

the old is broke so that why i had to change and it would never fit right
                                     
                                       

                                      new one
 

                                       old one

The circuit boards are identical. I think that is what we were trying to find out, right?

[hotrod24]

yea and if i can use the new in my 78

Did your old one ever work? If so, it looks like you should have no troubles, then.

[hotrod24]

yes it worked but it is broke

Same cluster.  1978-80.  You could swap everything over to the housing if you wanted...

[hotrod24]

so both of my clusters are 78-80

[Captkaos]

yes, that is correct.
If it was a 77 cluster, you would see a hole where the oil pressure gauge it for a metal line to connect to.

[hotrod24]

why do i have a hole where my battery gauge is it is on both of them

[ccz145a]

An ammeter would have used that hole and the top one would be empty. But the connector would have been + instead of ground. Your whole system's current would be flowing thru the meter. That is why you can't use an ammeter circuit panels with the voltmeters and visa versa AND why so many questions were asked before we told you it would work. sizzle, sizzle.

 i am just trying to make sure that if i get a new dash harness everything will work

I just re-read my post... It could have been read as a sarcastic response, but I did not mean it that way. You have put a lot of work into your truck, and I want to see you succeed, too.

[hotrod24]

thanks man i have worked hard but i did not take it that way you was just trying to help out
