During the course of trolling threads here (a great way to learn what I don't know) someone mentioned that a Series III 4 speed wouldn't fit in a Series IIa chassis because the crossmember under the bell housing conflicts with the newer clutch slave cylinder. Ought oh, I am replacing my rotten cancerous Series III chassis with a solid IIa! It turns out to be true. I had to 'modify' my newly powdercoated Series IIa chassis a bit today as I reinstalled the engine and transmission.
Here are a few pictures to illustrate:
Series III crossmember below bell housing just over where the slave cylinder would be, looking aft.

and Series IIa crossmember below bell housing (though this is from the opposite side looking forward because I forgot to take a 'before' photo)

The clutch slave cylinder would not clear this triangular support.
Here is the modified crossmember

and looking aft after installing the engine and transmission

I can not say enough for all the knowledge and help available here. Thanks to everyone, there is no way I would be getting through all this without your help.
