RPM and SPEEDO lights

[nascar]

Hope I got the right area here. My 87 GN had the stock dash lights (non-digital). The RPM and the BOOST lights aren't even close to being accurate. Can they be calabrated or replaced separte from the rest of the panel. I have one of the original 150 MPH speedo panels that did not use the converter so I don't want to replace the whole thing.

I have heard that Caspers Electronics has some parts to help out in this area. Hope this helps!!

They can't be calibrated or adjusted. I don't think Casper's offers much to repair these, get some good aftermarket guages, and you'll be set.
