Factory Tach and center gauge

[Z28DZ]

If you ordered RPO U16 the tach took the place of the standard large fuel gauge and a smaller fuel gauge was put in the center position (gotta have a fuel gauge). If you look closely at the U16 installation in the assembly manual, you note that the #2 part is decribed as 6431307 GAGE ASM. It also tells you that the dash cut out should be the same as for U35 (installer refer to U35 for dimensions). The only way to get the clock with a tach (factory) was to order U17. Of course, if you did not want gauges, the clock could be order singularly RPO U35.
