3 part #s for M6700, please help

Can users please provide in comments the Dell part #s for the following parts:

1) primary storage bay
not any particular storage drive/device, but the M6700 drive bay that ejects with the eject latch on the M6700.

2) secondary storage bay
not any particular storage drive/device, but the M6700 secondary storage bay (all black with holes and the "flap" (or whatever it is) to pull while removing the secondary storage bay/drive.

3) the mounting spacers (or "HDD Rubber Insert") that allow the 7 mm SSDs to fit well into the 9.5 mm space. Even if you plan to secure an SSD with screws in the secondary storage bay, for instance, it is difficult to align the drive while placing scews without a mounting spacer that will line up the screws and relevant screw holes/openings)
I have seen some of these (not from Dell) made out of plastic - usually 2.5 drive size of plastic with the middle cut out so only an outline remains. I have seen many M6700s with these mounting spacers as a small piece of rubber with several holes in it. The different variantions on this part should literally cost pennies/dollars to make/sell, though I am amazed that there seems to be no retail market at all for them.

Any help with part numbers please?
