71 340 Duster Tach

I've never seen a 7-8 grand Factory A-Body tach myself but I won't say that I'm an A-Body expert.
I've been into these cars since the mid to later seventies though.
I just refaced my tach with an overlay that has the redline per a couple of people's suggestions but still don't know if it's right for my SPD 925.

I think (without proof) I should have just used the white face because of the early build.

Oh and although I marked my housing for proper placement I feel the decal has shifted everything slightly counterclockwise.:banghead:
