The Eclipse I can't help you with. I know nothing about the DSM products.
On the Daytona you need to stick with and 84 or 85 transmission. They have a 6 bolt flexplate and three lug torque converters. In 86 Chrysler went to an 8 bolt crankshaft, a 4 lug converter and changed the pump engagement design. Is the Daytona turbo by chance?
The 94 has better options. First check to see if it has a lock-up converter or not. The plug for the lock-up is directly behind the base of dipstick. I'd bet it is a lock-up. Use an 89 or later model transmission.
