Tricky with an Mi4, it's one of the few cars on the market where the front and rear diff are not identical. If you put the spool in the rear the belt pulley will be misaligned, same for putting the diff in the front end, although because the belt is longer you don't notice it so much.

You could try a slight bodge by getting another rear diff for the front and locking the existing rear diff up with glue but I'd be tempted to trade the car for something that is easier to set up for drifting.

The rear diff works ok in the front. You might have to dremel the top deck a bit for belt clearance. If you demand a perfect fit, then an Mi5 gear diff is what you need.

For the rear, the cleanest solution would be the spec-r gear diff for mi4 with the spec-r thing that replaces the gears with a plastic piece that locks the outdrives together. Or just really really thick oil.

Actually, now that I think of it, an Mi5 spool might fit the rear properly, since the mi5 diff fits the front.

if you want a locked rear, why not just lock the diff, lots of way to do it, glue it, cut out pieces of cardboard, (the little header card that staples to the parts package works good) sand paper, tighten the crap out of it.

no misalignment on mine, you simply switch diffs, front to rear. flip them left to right and swap the belts left to right.
both belts drive off the same centre gear, so instead of the front belt running down the left side and trying to the run the ball diff that was in the back of the car with the belt at angle, you flip the ball diff and run the belt down the right side. perfectly aligned. same deal for the rear.
