Not sure what I'm going to do until I get the 741 back in and test drive to see if the whine is gone, it is driving me nuts. This is just a street driver with a modified 360 so not too concerned about breaking anything.
Thanks,
Wow, now I am confused. You are saying that I can take a pinion / ring gear set for a 742 case and put it in a 741? The spool must be different, and what about the sure grip packs?
