Back in the 80's I experimented with a v6 engine with a in and out clutch. Use the input shaft of a transmission which a transmission shop gave me. This mates with the clutch disk. The input shaft had its gears machine off to fit a taper lock coupler on a No. 60 change coupler. Another taper lock fitting on the change coupler connected to the input shaft of the EV motor which had a standard flywheel, clutch, pressure plate that connected to a transmission.
The chain coupler had a two piece bolt on housing that has a grease fitting on it which can be grease at the same time all the other grease fittings on the EV needed greasing. You need some flex at this coupler, because when the engine starts or you apply a violent acceleration, this allows the engine to thrust back and forth and from side to side. It is best to place the engine and motor on the same rigid plat form and than use donut motor mounts to connect this platform to the vehicle frame. I use all these drive mechanism from the Dodge Power Transmission Company. They also make a dynaflex coupler that bolts directly to the flywheel which has a taper lock bushing that would fit the motor which may work better than a chain coupler. The dynaflex coupler has more side to side and end to end motion. We use one of these units on a power speed boat that turn a jet pump. If I was to build another EV again, I would build a sub frame all out of aluminum I or H rails. The flat form bolts on these rails. The rail would be design to hold the radiator, engine, motor, transmission, drive line and a swing axle differential. You just pull four pins or four bolts and the whole works slide out onto a four wheel carrier like they do for jet engines on a aircraft. The battery pack could be unplug and can be slide in or out for major maintenance or replacement. In my existing EV, I built a sub-frame that holds the accessory drive, the motor, and transmission. Design the cross members to connect to the EV side rails so all I have to do is remove cross members that bolt up under the side rails instead on top. Use a floor jack with a modified attachments that replaces the floor jack lift point by just sliding this attachment on. I can remove all this assembly and replace it with a spare set in with a day.

Imagine having to crawl under your car to clean and lube the chain every month or so. That's something to think about for this Mustang hybrid conversion - how will you lube the chains, Ben? Curiously, one limited exception is/was early Solectria Force EVs. They used an exposed cogged belt between the motor and transaxle. Sales were on the order of a few hundred, though, so you could hardly call it a mass- produced automobile. There are a scant few others. I think one version of the Toyota Prius (2004-2009?) has a chain and sprockets somewhere in the PSD (driving the differential?). It's fully enclosed, however, so it's maintenance-free. I've never heard of one failing. Depending on how you define "chain or belt drive," another exception might be the FWD Oldsmobile Toronado (correct spelling) introduced in 1966, and still on offer into the early 1990s. It had a fully enclosed chain between the torque converter and transmission. The transmission was mounted next to the engine, facing "backward," driving the front wheels. The same "folded" front wheel drive system was also used in a Cadillac model, and in some GM RVs. FWIW, I don't know of any Toros that have ever been converted to EVs. It would be quite a challenge. They were monsters, very large and heavy, and I don't see any way you could replace that customized automatic with a manual. The Corbin Sparrow / Myers NMG EV also had/has a belt drive to the rear wheel, but that's really classified as a motorcycle, so I guess it doesn't count.
