atomarc, thanks for the reply...I understand trans. brake drum must be on aux. to work.

I have seen aux. Spicers 8341-C with no brake & no linkage that have come off of trucks with AIR brakes & AIR shift, so that will be an issue.

I see Grigg has disc transmission brake setup on his diesel project...nice work...and very clever.

Send me a picture of your '54 if you can, Thanks Jim D.
