Recalibrate 85 mph speedo to 140 mph
I was going to change to white gauge faces and I thought while I was at it, I'd get the ones with 140 mph speedo. Can I recalibrate my 85 mph to work properly with it? Thanks.

89s correct. Should you eventually remove the cluster to install a 145, consider replacing the stock bulbs with xenons.
