I am doing an 95 LT1 swap into an 87 with a TPI. As you all know the LT1 uses an electric input for the speedo. Unfortunately the camaro has a mechanical 85 MPH speedo. I am looking to see if a later model gauge cluster with an electric speedo will work (preferably from a 3rd gen). If not, then I am going to have to go with a full autometere setup which i am trying to stay away from. If anybody has some later model gauge clusters let me know.

 

Here I think this year had a pm gen that drove an electronic speedo. can anyone verify it?

The '92 and '91 gauges use an electronic speedo, but they won't fit in the '87 dash without some chop-work.

For some reason 1990 comes to mind......they might have had electronic speedo's and the older gauge layout, but I'm really not sure.

 

or use lt1 guages with a dash swap
