Saw this fellow on 69 again today though...
Have you ever considered that 8603J has been probably out from
69 long ago to SP? I thought about this for some time, then didn't
know which bus was stuck on Sv 69. Then 8662M came along..so
perhaps 8662M sub 8603J? 8603J should be SP already anyway at the
rate it cameos around for months.
As for what replaces 8662M on Sv 8, perhaps you wanna check it
out too~
