Does anybody know anything about the TR-3160? It looks like another potential option, used in the ATS from '13 on, also under $1,000 for a unit with under 60k on it. Looks like you can get a yoke adapter that bolts on to the output flange to be able to use a slip style driveshaft. Though the starter provision is on the wrong side of the bellhousing. The ratios look a little better than the AY-6.
So working out some of the costs, just to get a ballpark, has anybody had to get a custom (not a special racing super strong version) slip-style driveshaft? I would ballpark that around $400-$500, based on what you can get one custom made for a truck at one of the online places. Unless there's a good reason not to use an adapter on the block, I'd probably have to pay a machine shop to get the dimensions of the bellhousing bolt pattern relative to the input shaft centerline (unless that info is online already), then waterjet an adapter plate and get a custom clutch. I can get the adapter waterjet for around $60, depending on how many holes there are. I figure that a custom clutch is going to be around $400 (that's what it was for the Bonneville anyway), and I'd spend around $100 adapting my clutch line unless by chance the quick disconnect is the same.
So $1000 for all that, might have to get creative with the TIG to get the shifter, starter provision, and tail mount worked out. Plus the cost of the transmission.

but way quicker.
