Ant,
Why not put any gages that anyone wants in one of these cars? No matter what you put in they are and will always be just Replicas. Some people go to extremes to make tham look as original as possible and that is great. I went the other way and made mine look as un-original as I could as I thought that would avoid some of the Is It Real questions. We all built these cars to suite ourselves except the purists, and this is in no way a knock on them. I admire looking at one that you have to ask if it is original. I use VDO gages and love being able to calibrate the speedo for a gear or tire change by just driving a mile and pushing a button.
