It is true that some of the hubs and components have turned up to be machined under size.
No telling where the actual part was manufactured.
I did learn early on , to check each hub with a shaft of the appropriate spline.
Bobby, that doesn't help you much at the moment unless you have a spare input shaft laying around.
If you are at 3/4 now,...no, that is not enough.
If you measure through one of flex plate holes forward to the machined bellhousing surface of the block , you will see that the converter pads need to be back from the trans case surface by that amount, plus your pullback clearance...At least .900 plus but usually 1.00 or more.
The pilot (what some have called the snout) has to be 1.702 or smaller on a GM V8.
The hub is what goes in the transmission. Again ,not a snout.
