Need Help With '17J

[jdonaldson]

I'm well into the reassembly of my '17J project and need advice on the top of tank screws. I've seen what's available online for mostly '18 and up but it looks different than the fillister head screws the spare parts directory calls for. Which is the correct fastener to use? Also, should the metal strip on the top tube be the only item drilled and tapped for these screws or does the tube itself get tapped? Finally, is there any information on the tank buffers available? I have no idea what these look like or where they go.

Thanks for any help.
