Hi group. I am in need of some information.
I am looking for a very specific application adapter plate. Some 20 years ago, a number of Chevy P30 delivery vans were factory repowered from gassers to 4B Cummins engines. The adapter plate was designed to bolt the Cummins B block to the TH400.
Now question being, Does anyone know if the adapter was a GM part or a Cummins part? Or has anyone ever even heard of this piece? I am searching for one.
thanks.
