This is rubbish in relation to the gearbox fitted to the V8s!!!!!!  The part
number for the first and secong gear synchro is 22H 1167 and the third and
fourth is 22H 1168 for both the 4 cylinder and V8 cars.  My authority is AKM
0039 - the factory spare parts manual.

Please get your facts right before making statements!!!
