Several years ago I bought similar replacement "padding" from Mcmaster Carr.
Good Luck

This is a blanket the size of the tank that covers the whole underside.
A friend on mine has one on his Ten.
Mine doesn't have one
Never seen a blanket, but there was an optional heat shield. It used longer cylinder head bolts to fasten and curved upwards between the exhaust manifold and fuel tank. I had one but sold it. Knew I would not need it for recreational use.
Unless you plan on using your TEN for all day field work...you will not need it. Mine has never vapor locked on the hottest days even when plowing for for a solid hour.
I would leave it off. Blankets around anything hold moisture for very long periods of time causing other problems.
