MBCluster only work on the cluster and instruments....not the plastic lense.
There are some guys in LA (North Hollywood Speedometer & Clock) that refurbish them and sell them for $150, plus they want your old one as a core.
Too much. $100 is a fair price.
Probably better off looking for a whole cluster for $150 to $200 and removing the lense.

Then at least you have some other spare parts.
