Take this recommendation with a grain of salt, because I can't guarantee the clones pickups mirror the design of actual Rick pickups.
I'd do toaster neck, hi gain bridge. A proper toaster is an alnico-poled, low gain pickup closer to a Fender singlecoil somewhat analogous to a Fender single coil. The hi-gain pickup is a screw polepiece, rod magnet pickup with more mids, higher output and less immediate string attack, somewhat analogous to a P90.
Bill Lawrence noted many years ago that the average player prefers their neck pickup to have rod magnets and their bridge pickup to have bar magnets. After this many decades of P90s and PAFs in bridge positions of Fender guitars, it really seems he's right.
Between their construction, output and tone, you'll likely prefer the hi-gain in the bridge if the toasters are anything resembling vintage spec.
Here's a video relevant to OSG and your question - a
Cyclone with hi-gain in the neck and a toaster in the bridge. You can hear how overwhelming the output and bass of the neck is vs the bridge, which maybe some people would be into, but the other way around balances a lot better.
