What year is it? I have a couple dash panels from early ones and one
from a 76 240 that is probably not much different from the 73-on.
It takes a little mechanical skill but not really that much, you just
have to be careful not to break anything.
Many of them already have given up because of a plastic gear coming loose
on a shaft. On the oldtimers, working odometers are getting fairly rare
for that reason.
