Procedure for making adapter plates

[Crosley.In.AZ]

An adapter in the making.... the makings of  version 1 design

A photo with a powerglide tranny with the bell housing machined off...... a large chunk of aluminum in a round shape.  A bell housing in the back ground.

The engine of choice?  A Mazda 13b

Version 2 of the adapter is different, I have no photos of it yet.
