Thanx guys
We appreciate You're responses/help as I'm not sure exactly what year 5.3L I've got . It took me a while to find out there were #'s on the drivers side block deck behind where the cyl. head resides that have been partially sanded off in the cleaning process . Maybe a magnifying glass and I suppose I could perform some sort of acid wash/development similar to the police procedure for identifying filed #'s . Anyway thanx again .

1 thing I found about rod differences
1 thing I found out about the rods since I first posted this is the 1st design uses a semi-floating "pressed" pin and the 2nd design uses a semi-floating "clipped" pin .
