Most of these "first design" Glide trans brakes are virtually all the same; sometimes the only difference is in the color of the separator plate. I'm going to guess yours is a TSR (RIP Carl Munroe), especially if the separator plate is yellow/gold anodized. Do you have the solenoid? Some of the kits also include a different set of reverse clutch piston return springs. I think Crosley will have a more accurate answer than I. Butch/junior stocker.
I might be interested in your valve body depending on your asking price. Thanks.
