3B tranny same as MC-2 tranny?

Okay, thanks.  That makes sense I think, since the '84 4kq had the (more desirable for some) 3.89 gear ratio, meaning quicker acceleration due to higher rpms for a given mph.

So, how about this for a bastardization/cost savings?  Can I put a Type 85 016 in a Type 44, such as an '85-87 4kq tranny in a 200q20v?  I realize I would be backdating to a locker diff, but this would give the correct gear ratio I believe.

Would this tranny fit the 200 chassis?  *wrings hands*

Thanks,

Ken
