Motor Mounts

This is tad old thread, but seems appropriate place to ask: do 2265 and 2469 motor mounts interchange? I have -65 Valiant with blown 360 and the motor mounts are just completely shot. Long term plan is to move into solid mounts, but I need to replace the mounts before spring just to get the car running and driving again. I think that having 2469 mount at least on drivers side could limit the twist. Polybushings.com states that their poly-mount would be replacement for both 2265 and 2469 so that makes me think that I could replace the 2265 mount with 2469 for now? For the record, the car is "old school" race car and does have chain bolted to engine on drivers side mount, but that seems not to be enough to stop the engine twisting (at least with the shot mounts).

EDIT:
For the solid mounts I'm looking for example these PLYMOUTH Moroso 62540 Moroso Solid Steel Motor Mounts | Summit Racing
With that price I could order and swap those in right away, if I could be sure that they in fact fit the Valiant with 360 and will be direct replacement for current mounts.
