why not install a factory tach from a 71-72 B body.
Because all the existing gauges would have to be changed...
i am sorry, I assumed your RR had the rally dash with a clock instead of a tach.
this is how my 72 RR was.
all I did was buy a repo tach from charger specialties and wired it in. only took a couple hours to do it.
Never saw a 72 RR without a ralley dash so don't get the response either.

there are 2 different rallye clusters
one came with either a clock or tach
one came without both a clock or tach
the one without has a totally different gauge layout
so it will not accept a tach or clock
it has no room for either of them.
