Thanks guys,
He came over yesterday and we both went at it. He took the center section home with him because i do not have a vice. There's just no room at all in my two car garage. It'll be different next time around when i buy another house. I had the car on stands when he got there with the wheels and brake drums off ready to roll. A drain pan on standby, tools laid out and chompin at the bit. He's a nice guy and i found out that we were both laid off from the same company years ago.
When we dropped the center section and looked at it, the outside surface of the sure grip clutch was chewed on pretty good from what he said must have happened at the track (the car was raced for a while by previous owner). Although the 410 gears that are currently in it look pristine. He figures a ring gear must have came apart at one time or another and did this scoring on the cluth surface. He assures me that the integrity of the clutch surface is not compromised in any way. If he sees anything inside when he swaps the gears, he will let me know.
The sure grip has been working flawlessy while i've been driving it. When you spin the clutch around, you can see tooth marks consistently all the way around with one that is pretty deep. It doesn't look like the scoring would make the clutch housing come apart but who knows at a later date. One thing for sure is that since i've had it (last fall) i've really hot rodded it quite a bit with no problems and i will be less likely now with the 3:55 he's swaping into it so we'll see down the road.
