Title: help identifying diff Post by: funkafide on September 04, 2007, 04:47:56 PM can anyone please identify this diff.
it's out of my fc and i guess it's a standard fc diff however i'm not 100%. a previous owner had put a floor shift in but engine and gearbox were removed prior to my purchase. am putting hr disc front in (202 & 3speed column) and am trying to work out what to do at the rear. ..... that didn't work.. will post pics as soon as i work out how.. stay tuned.

From memory I went that way on mine because we decided it was easier to modify the saddles for the diff housing (ie cut the mounts from th FC housing and weld them to the HR housing) than it was to muck about with the backing plates to fit the HR wheel cylinders.
