Speedometer for '87 4kq

[Andrew Buc]

In the last couple of months, after the speedo in my 4kq failed, I've  
been through a couple of wrecking yard instrument clusters. In both  
of them the speedos failed in fairly short order. I came up with  
another cluster (from a non-lister) and sent it off to North  
Hollywood Speedometer to be gone over.

Today NHS touched base with me, and it seems that below the tripmeter  
reset knob there's the text W=1580. They need to know the  
corresponding text in my OEM speedometer so they can swap out the  
gears if necessary to make the one I sent them read correctly.  
Unfortunately I no longer have the OEM speedo. The speedo I have in  
there now seemed to be accurate until it failed, and it says W=1650,  
but I don't want to give NHS the go-ahead just on the basis of that.

Anyone out there with a 4kq--what does it say on your speedo? Thanks.
