The first LM bodies came on a MR02 chassis. Don't worry about the ball diff, as long as it says for LM, it's just a longer shaft. You can take the parts off and put them on a standard length shaft. Just be aware mixing parts between manufacturers sometimes doesn't work well. The rear end of an 02 or 03 are interchangeable.
I've tried the O ring. The one I tried lost its shape and started to wear little bits in the gears, maybe you'll have better luck.
mikedw - Thanks again!
I found out too after researching that link you posted that the BRZ body is RM so I went with a 599XX. As you said, the 98mm setup (like my 458) has EXCELLENT balance between straight line and corning stability. 599XX is also 98mm MM.
Oh and the LM shaft, thanks for that info.
I noticed that the damper mount bracket is different on the LM so I ordered that as well for this conversion to 98mm MM.
I too think the o-ring inside the diff will breakup in time if left as-is. I am thinking about putting a thin washer or shim between the o-ring and the 3 bevel gears next time and put some Green Slime between there to prevent direct friction against the o-ring. This should prevent breakup.
My MR03VE (LM) and KT18 arrived so I will work on that later today. Front aluminum knuckles and ball diff for it expected tomorrow.
I have another Orion charger and 800HV AAA's coming to me this week as well. The 800HV provides the punch I want.
