I would prefer an October dated REAR BUMPER core, better if dated before the 20th if possible.
NOS is acceptable too.
I may be interested in other dates for a core since my front is NOS anyways and not correct already therefore it may not be unreasonable to have one (off dated) the same on rear.
If anyone is VERY HAPPY with a quality aftermarket, let me know your take on those too (the "good", the "bad" & the "ugly"). I might end up going that route anyways (at least for the time being) if I don't find a good core or extremely nice 'otherwise'.
