1970 GS POP decode

Need help decoding, I know the following:

179 is dk brown interior
58 is harvest gold paint
F is dk brown vinyl top
vin is obvious
SR 455/350hp
BA th400

what is 184 after SR
what is OK
what is N
what is 309 after BA
what is 12 68?

 

maybe one is for notch-back bench interior

 

OK is rear end code ,, is 2.93 open

 

2.93 open, one of very few things I dislike about my car.

 

thanks Brad. I guess it makes sense if protecto plate was used for warranty purposes.

 

...1, 2, 6, 8 are option codes. Should be page in assy manual with chart if no one knows offhand. POP option codes only use single digits 0-9, so only partial option list. For '71 they're PB, A/C, AM/FM, and PS...may be diff for '70...

 

N is the build month code
N = November (1969)

 

build date is consistent. car was delivered 12/1/69
