[TR] Read drivers lever shock (damper)

[thenicholls at verizon.net]

1972 Triumph TR6, up on ramps this weekend.  The two bolts holding the lever shock to the body were loose.  Tightened, other side fine.

I see on the archive someone suggesting longer bolts and a nyloc bolt on the other side.  

I used a 5/8th socket, what size bolt, what length bolt, and nyloc should I get?

Thanks and Happy Memorial Day to the list.
