The flex plate looks good not bent, or chewed up.
When ever I buy a starter from summit there is only one style for the 350.
Order a SET of NEW 350 Starter bolts from GM, If you look, those are knurled..after so many changes, they no longer fit..and give the starter "Wiggle" room..
Also, If not using it, get a rear brace for the starter..
The open inspection hole will contribute to the noise level.
