1966 904 into LA360. Where do I find the snout bushing?
You wanted a source for the bushing. We gave you that.
Despite searching I can’t find any recent reference to such a bushing.
I can’t find any reference to this bushing in contemporary media.
You can't find any "recent" reference in "contemporary" media? A quick search of "convertor bushing" in the transmission forum turned up at least a half dozen references, some new, some old... old posts are just as valid as new, these things were built 50 years ago and they still work the same way. That's why a 50 year old FSM is essential to the hobby.
....is why the adapter bushing is needed?
Now you poo poo the reason it's even needed- what's up? You do know how these fit together, right?
Don’t understand the need for a bushing
The convertor nose needs to be supported, on center, by the crank (that's why there's a nose on the convertor in the first place)- when you mix and match parts they need to be adapted to work together as originally designed.
If you don't believe me, go ahead and throw it together.
Then post for help diagnosing your mysterious "engine vibration".
Then ask why your B&M flexplate keeps cracking... and tore up the convertor... and pump...
Oldmanmopar is probably right, you should just use a later 904- better internals, no convertor snout issues; direct bolt-in to your '66; linkage swaps right on, uses the same driveshaft.
