Thank you Jimmy Bush. I just got the phone with a buddy and that's pretty much the very same way he explained it - except he didn't mention about the cam drive pinion with associated nuts, keys, and washers in place. Wouldn't hurt to these extras as well along to the machine shop.
Now, if we can only be sure on the correct balance factor. I know the T120 called for something like 85% but something tells me that they used a different number for the 750's.
