Yep, I had my neighbour do the build, he's a professional tranny guy. But
fourth got swapped, the AGB fourth just does not fit the 3.94 pinion (which
I got from Peter, new). And fifth got swapped because it will drive you
insane otherwise, I'd like to do Klaus' too. (and may as well do the diff
too while you're there, hell, it's only money). I have pictures of the two
pinions, they don't look at all alike, the AGB one's longer (and I think
skinnier, IIRC, the .org gear chart would confirm that). It's a
frankentranny, just like all my stuff ends up, it seems. Appropriate for
Oct 31, no? :)
