Help finding Mazda Part Numbers

[Raksj04]

So I am rebuilding my engine. I wanted to know If there is a list of rebuild parts. I am on the Mazdaspeed parts program, good discounts, and I am having a hard time finding the numbers I need. Since sometimes they list 3 to 4 part numbers for the same item and a lacking description, but the prices are different. I have used Atkins Rotary for the side seals P/N and the springs. The Mazdaspeed site gives me a 404 error for the rotary rebuild list. on my work computer and home computer. right now I am looking for apex springs.
