Trying to find the Part# and Pic (if possible) of the correct Tach for a Rallye 350. The car is a F85 Sports Coupe (V8). Came with the M20 wide-ratio 4-speed floor shift transmission. I have a picture of the current instrument cluster in my gallery.

Thanks for any help.

 

You could not get a tach alone in these cars. All 1970-72 Cutlass/442 models were available with the optional Rocket Rally Pac, which included the concentric clock/tach in the RH pod and the temp/oil/fuel gauge in the LH pod. Repros are available. (Ignore the fact that they appear to be different diameters in this crappy photo that I stole from Year One)

 

Joe,
Thanks for the reply. That is what is confusing to me. It doesn't list U21 (Rocket Rally Pac) on the original Shipping order for the car. Would that have been standard equipment for the 1970 Rallye 350? I am assuming because it is a 4-speed standard transmission that it came with a tach, Is my thinking wrong?

 

Your thinking is wrong. The Rally Pac was an option, not standard equipment.

 

Here is the dealer bulletin that describes what is included in the Rallye 350 package.

 

Thanks again,
So, if the clock and tach was not listed on the Shipping order, what would have been in that place, a clock blank?

 

Looking a lot like this:
