Starter nightmare 2007 Tundra 5.7l 4x4 longbed

I am extremely handy and have always worked on all of my vehicles. My starter went on my 2007 Tundra and I am in the middle of this horrible job. I went with o.e starter . Of course the signal wire clip cracked off (due to all the heat) finally was able to get that which was fun. But the cap that goes over the main power nut is cracked off and I can't find how to purchase anywhere. Does anyone know the part# for it? I have searched. I have called dealers and junk yards. Please if anyone has any help for me?

 

This one??

fortunately that is the one that I was able to find. Thank you though
This is a cap/cover that goes over the nut of starter wire to keep it from shorting out.( main power nut)

 

Just zip tie some rubber on it?

 

No room to do that

 

Are you talking about the switch magnet??

 

Are you talking about the heat shield? I've done the starter and I don't recall any cap or cover that you're talking about. Only cover/lid/cap I know of is the heat shield that bolts up to the side of the starter.
