4 KQ gearing

[Ron Wood <vw-audisport@worldnet.att.net>]

In an earlier post, Glen mentioned that 84's have a 4.11 final, whereas
the 85-87's have a 3.90 final. I thought that was the case, however, in 
my microfiche for the 85-87 4KQ, they list a 37/9 (4.11) ring gear set.
I know the gear ratios are different as well, can we verify the 
ring/pinion changes as well ? A friend just got a boneyard 86 4KQ trans 
for his Quantum Synchro which lists a 4.11 as well, if the later trans 
do have a 3.90 this wont work for him.
Thanks
