My car is a 3 of 77 production 280. Does it have a r180 rear differential, or a R200? Also, visually what are the cues between the two (how can I tell which it is?) Please guys, this is really crucial...

sorry joshua but you are wrong. the R-180 can have either style of output shafts, the single bolt type or the 4 bolt flange. i think the single bolt type was used in auto. trans cars and the 4-bolt type in standard trans cars. the 77 should be a R-200. the body of the R-200 is larger and one piece with rounded sides where the R-180 has flat side covers held in place with 5 bolts. hope this helps.
