i just got an obd2 gsr distributor, and its been a while since i've seen a gsr distributor so i'm not sure if its oem. its stamped td84u, d3179 on the part that contacts the head. its got what appears to be 2 6mm head bolts near the bottom ear. i don't have the right size screwdriver on me so i can't get the rotor off to see what brand the internals are.

is it oem or aftermarket crap?
