I put the bracket in, with 3 of the AT-667's in it, and tried to put the cover on. Very big mistake, the right front corner bolt boss is 2x bigger than it is in the base casting, leaving zero room for the alu bracket. Took cover to mill and as they say in a hot rod shop, bore till you find water, which despite watching for nervous paint, I did find.
The upshot was that I pulled the backgear countershaft, took it to the vise, knocked the gear shift handle off it with a brass drift, filed off the setscrew burrs, put a screwdriver slot in both ends of it, slid the bearing and the backgear about 3/32 to the right so I can put the little piece of screw for the index pulse on the other face of the gear. But I'll have to make another block of alu to put on the left side of this one for the index. Put the handle on while the shaft was turned to engage the backgear, used the screwdriver slot to set just a degree short of full, rumbling the neighborhood engagement and set the setscrew again. It had been set since day one for way too heavy engagement. Runs at least 30 db quieter now. Even my ancient ears can put up with that. So I have a little leak in the cover I'll put some filler in & polish smooth. And a coat of paint.
