I have one, possibly 2, in a pair of 1959 Grumman bodied step vans on Chevy Dubl-Duti forward control chassis.

One of them I've taken out and the tag shows 2987S. This is on a 235 with Hydramatic.
The other looks outwardly the same except no ribs on accelerator pump well, and no tag. Also a 235, with a manual, but may have had a Hydramatic originally, not sure.
