Can anyone recommend a source to replace the erratic Tach in our 79
Archer. I'm looking for "new" and have seen the Mitchell replacements
with custom markings as acceptable. But since this is for a club
airplane which is billed on Tach, I would like to get an identical
Tach
with both tenth and hundredth digits. I find this makes for less
fights over who pays the half digits.

Thanks in advance.
Mike.
