Missile Command Board & Video Pinball Board ?'s

Alright I need to replace some chips on both boards and have a few questions before ordering.

Atari Video Pinball:

I need to replace one of the 6502's, now on BRs site I see that there is an A, B, and C. Is the only difference the mhz? And which one should I go with, I don't think the manual specified?

Atari Missile Command:

I need to replace what I believe are ROM and PROM, I am a little confused looking at the manual but these are some of the numbers I have pulled off of the chips:

035824-02
8039c

035824-02
8041c

035823-02
8039

035820-02
8042c

Are these all custom chips or are they something I can buy somewhere? Well I guess I could technically buy custom chips, but are these something I could easily buy for a decent price.
 
For the Atari Pinball, a 6502A should work fine.

For the MC, those are some of the program ROM chips. If you have six 24-pin sockets on that end of the board, you should have the following 2k PROMs:

035820-02
035821-02
035822-02
035823-02
035824-02
035825-02

It sounds like at the very least you have a second duplicate chip that shouldn't be on the board.

BTW I can burn the chips you need.
