1975 scamp brake conv

I haven't pulled the 6 out yet . I'm jumping on this tomorrow. I picked up a 318 with 904 still bolted on. The guy painted it blue.....whatever. I have to go over it in my shop and check intake manifold and cam height ect. My car runs great on the 6 right now so I want to gather parts so my wife and son don't grind me for down time.
As for ball joints, I will measure now.
I have drum brakes BTW. I need discs for front.
