1946 Convertible parts needed

Restoring an early 1946 barn find after a 56-year slumber.

Looks like it needs two ragtop parts-the knob to lock down the top, and the rear window assembly.

(oh, and a gym bag full of $$)

Any leads would be appreciated

Also the horizontal sheet metal shield between the radiator and the grille, same as all models

Thanks
