That cluster is for a gasser. Do you know if the odometer still works? I've been told that you can use parts from one to fix another, having a working odometer would be nice.
It looks like MK2 stuff,.. because of the plug probably an '85.
Nah.. that's a mk1 gasser. It has an OXS indicator and no glow indicator.
MK2 clusters have screw flanges at the bottom, not posts.
