The
parking brake hardware on my '47 was long gone too. If you have the 'Link' as identified in Fig. 21, you probably need the R and L 'Lever'. It took me a while to get everything I needed but, I posted in the Swap Meet under the Truck Parts Wanted forum and a Stovebolter came through for me. Remember, these are Huck brakes and not Bendix brakes on the 1947 second series.
Exploded Diagram It's for a 1 ton rear brake, basically the same design.
Good luck,
