rear
YEP... That carrier in the 'O' type may look like a 8.5 but it is NOT. The bolt pattern is slightly smaller bolt circle and the inner ring gear diameter is also larger. The pinion is another difference. The 12 bolt 'O' type is 27 spline and is shorter than the 8.5 30 spline pinion. JUST WILL NOT HAPPEN....with out some serious machining...lol.
What ratio were you going for? |
