Too bad that overdrive section of Vintage Auto Garage only handles R10-11 units but that is kind of to be expected because the same is true with 5th Avenue Garage's repros. That combo relay and power substitution box is kind of expensive though for being capable of only 15 amps and for such a brief period.

Packard never used the R10 but the 6v R11 stayed around for 6 years so glad there are repro parts available for those cars. The 48 and earlier R9s have no option but to use the original relays and solenoids as nothing is repro'd for them. Because of the electrical differences and added complexity, except for a modern universal kickdown switch, nothing current or specifically for an R11 will work on an R9. The R6 in a 39 and the R9 in a 40-48 will require some kind of independent power at 6v and for a margin of comfort, 20+ amps to be connected at the input fuse to the relay box just as if it were being connected to the battery in the car.
