SRT/4 motor in my '65 Valiant?

You might look at a Dakota bell housing that was used on the 2.5 4 banger with the 5-speed. Might be the same as the 2.4

That would be a great ride!

They are real close, and few people have made them work with slight modification to the starter and drilling a bolt whole in the bell housing to match the 2.4.
