WTB: Black C2N, 6540 ROM, 6550 RAM (PET parts).

So I got this PET 2001-8C, it has the wrong kind of tape drive, it's the narrow kind with white buttons and the cut off corner.
Which seems to be the version for the "blue PET" and doesn't fit the shell properly of the 2001-8C that I've got as can be seen below:

I took a picture of the removed tape drive and possible candidates - although the wrong color and year (1979).

I thought the sawed off corner was some kind of hack but I have seen exactly the same on other internet images so it seems to be like that from factory - I guess not to hit the heat sinks inside the PET. Case could have housed four C batteries and a speaker it seems, maybe a handle in the front. I'm guessing there's some other brand of tape deck somewhere with the full case intact.
Another example of this white button tape deck:

So I'd like to get the proper model, this one shown in the middle:

I also have a flawed 013 ROM so I want to find an original MOS MPS 6540 013 - I thought I'd ask at least before making an adapter. I'm also suspecting bad 6550 RAM, haven't found a handy way to test these properly yet though.

I have gotten a proper tape drive/datassette and made replacement RAM and ROM for the two that where broken, heatsinked the other chips.

Would still be nice to get original RAM and ROM chip as stated above, if possible.
