The 78 is 7.8 inches the 86 8.6 inches, with that being the size of the diff centre. Link to comment Share on other sites More sharing options...

falcon73 Member 163 Member For: 18y 6m 30d Posted 11/12/07 02:27 AM Author Share Posted 11/12/07 02:27 AM So if I get diff gears from a Borg warner M78 diff centre, like higher gears they would bolt to the centre OK or if I got a centre from something like a B/W that has the m78 model number it should bolt straight in.
