You will want to swap the gauge cluster for a MK3 cluster, cause the MK2 uses a speedo cable, the 02A will have a speed sensor that works with the MK3 cluster, other than that I think you will be OK (Other than converting the clutch set-up).



Edit- you may be able to use the corrado cluster, that should work with your MK2 dash since the corrado is a MK2 car and it should have the speed sensor set-up for an 02A.
