Freshen up a 904 in one weekend. Doable?

Alright. Rebuild kit on it's way, TransGo kit sitting on my bench, youtube videos downloaded, pdfs saved.

I still need to order a sprag kit and thrust washer set.

Just to double-check, will these be good?

Thrust washer kit.

Sprag kit

I was ready to check-out but then noticed the thrust washer kit says '74 and later. Mine's a '72 and I'm not sure of the difference.
