Right on.  Even though I love the shift feel of the ribcase, for the
reasons you mentioned, I am planning to do this:

Do you know why these splines keep going?  This doesn't sound too
Has this happened to others who have made the swap?

I have to agree.  I attempted to remain a purist through SIX ribcase
transmissions (original, shop rebuilt, used, british rebuilt, backyard
rebuilt, shop rebuilt).  I gave up and last year installed a WONDERFUL Datsun
all syncro overdrive 5 speed out of a 78 B210.  The swap wasn't easy, and we
did have to be creative with an assortment of parts, but we did it without a
kit.  And although Mini Mania claims it doesn't require any cutting, I did
have to cut out the crossmember and fabricate a removable one.  Brief

Install above combination, turn key, slip quietly into 1st gear, and drive
away with big smile on your face.  At freeway speed look at tach and smile
again..3000rpm=65, 3500rpm=about 75, 4000=about 85.

One year, about 5000 miles, no problems.  Smile again {:>)
