Venom XR6 Member 1,460 Member For: 22y 3d Location: Geelong Victoria Posted 01/12/07 12:47 AM Share Posted 01/12/07 12:47 AM Ford diffs usually have a small metal tag on the bottom of the diff centre, apart from that I don't know how else you can tell bar the physical size of them. The 78 is 7.8 inches the 86 8.6 inches, with that being the size of the diff centre.

falcon73 Member 163 Member For: 18y 9m 15d 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.

falcon73 Member 163 Member For: 18y 9m 15d Posted 03/02/08 02:36 AM Author Share Posted 03/02/08 02:36 AM M86 into a m78 or n/a 6, you need whole diff centre housing driveshafts not sure on the brake backing plates, as the m86 is larger Link to comment https://www.fordxr6turbo.com/forum/topic/40015-m78-or-m86-diff/#findComment-629507 Share on other sites More sharing options...
