gs750 to gs1000 speedometer

[Gregory]

Are the 1978 gs750 and 1978 gs1000 speedometers the same?

I have a chance to buy one but want to make double sure they are interchangeable.

I was wanting to keep it stock...so I just wanted to swap the speedo from that cluster over into my gs1000 cluster.

When I checked the OEM numbers they were different.

I also wondered whether the L model bikes speedos would swap over into the E cluster,

I believe you will find that they are different.

You need to have them measure the diameter of the bezel and the spacing for the mounting studs.

Does the speedometer you are looking at have the two extra wires for the reed switch?

I cancelled my deal with the guy so I am back to square one.

I did see a whole 78 1000 cluster on ebay this morning for $45, but it would need the face plate changed out to the mph instead of Kilo

Those are 'C' model gauges. They are missing the reed switch necessary for the self cancelling turn signals.

They can be converted over if you are ambitious enough.
