rebuilding 4 speed can gears between 2.47 and 2.66 be inter

We are rebuilding a 2.47 ratio 4 speed and having trouble finding a second gear--Can second gear from a 2.66 ratio 4 speed be used in a 2.47 ratio--there the gear count (34)---what is different between the 2 gears--

In order to change any gear you would also need to change the bottom cluster to one with the corresponding gear. Since these are one piece clusters, I think you're out of luck.

Yup - as was said you have to swap the cluster and the gears between them. Not just the cluster, or just the gears.
