Hello,
My dealers parts book is not the lates edition, so some of these numbers could be later versions which are not listed in my early book.
Here us what I found,
113 997 01 81
firewall heater tube rubber grommet, part #60 group 83 in your owners parts book.
A 113 826 00 12
no match found try group 86 in your owners parts book.
000 492 01 83
this is the heat insulator shield for the exhaust hangaers. Two of them are used on the system. See part #13 in your owners parts book (group 49).
009 545 93 28
Not an exact number match, but looks like an electrical plug see (group 54)
A 111 264 00 32
this is the small shaft in the standard transmission which drives the speedometer cable gear. See #93 in your owners parts book (group26)
A 111 992 05 10
This is a shift rod plastic bushing. See part #107, group 26 in your owners parts book.
A 009 545 30 28
no exact number match but seems to be grouped with more electrical plugs?
A 309 261 07 80
no exact match the prefix "309" is very unusual!
A 107 471 16 15
no eact match but the prefix "107" indicates that it was used on the later W107 chassis SLs also.
