I mentioned in post #45 on this thread... I found the correct narrow block 5 speed at a Upull near Seattle, WA.
I'll be installing it some day - since I don't have a place to do it at the moment. I will probably go back to Sacramento (I'm in Carson City, NV at the moment) and do it there.
I pulled the the bottom plate off and the gears look good. No chips and the synchros still have teeth on them. I did an inital clean up, but need some stronger degreaser to eat the oil deposits on it.

I also read a thread somewhere that mentioned a performance cover - I don't remember much, maybe it was stronger and had cooling fins on it (?)
If anyone knows about this, please post or PM me. Tnx.
