I think this cluster started life as a 1981 or 82 C10 Chevrolet factory tach cluster, IIRC. I added 1971 Camaro Z28 150mph speedo (standard camaro is 130mph) and base 71 camaro 7000rpm tach (I think the Z28 had a 8000rpm tach)
I replaced the guage pointers on the truck guages with those off the camaro guages. (except for the fuel guage I never got that one changed)They are very easy to swap and makes it look factory. Camaro tach/speedo are very close to the same size as the ones I replaced and were an easy swap/.
