8.75 rear in 71 swinger slant six car?

Just curious, what is the gear ratio on that 8 3/4, 3.23 ?

Maybe 2.76.

67 Dart had the 3.23 with a 170 slant.
72 Duster with 225 slant had 2.76
74 Dart with 225 slant had 2.76
All had the 7 1/4s, but just for the ratio sake.

If the 8 3/4 still has the ratio tag on the pumpkin bolt yet, that could be a clue as to it being original. If the ratio tag is missing then maybe someone swapped it in cause the
7 1/4 was clunking ???
