Greetings,
 
I had a pretty productive day at the Rev-3 work session.  The main thing remaining is the spinner cutouts, which will be a new experience for me, since I've somehow managed to always have spinners that were pre-cut.  Man that's one serious looking prop :-)
 
Ed, I either lost a few hours to you, or gained a few days (or more).  My plan was to replace only the drive, and not remove the plate or anything else.  Unfortunately, my new input shaft wouldn't fit in the old dampener splines.  It was just too tight to try to make it go.  Sure enough, the old input shaft was a fairly loose fit in the new dampener plate, so there is a difference.  I ended up having to drain the cooling system, remove the rads, remove the plate, and replace the dampener plate.  This was only a couple hour delay for me, but if your new input shaft doesn't fit your old dampener plate, you're screwed, since you don't have a new dampener plate. 
 
I called Tracy, and he said Ford wasn't all that precise over the years, and that it sounded like my old plate was on the tight side, and the new plate was more normal.  He chose to make the C drive input shafts a snug fit, so it just won't work with my old dampener plate.  I hope you have better luck.  He said it was possible to lap the splines to fit, but wouldn't be worth the trouble for me, since I already had a new one to install.  The old one, being tight, is a better fit for my old B drive anyway, so they might as well stay together.  The B drive is going to be for sale, BTW.  
 
Cheers,
Rusty (should be running, if not flying by Monday)
