Anyway, before I waste my time fiddling about and fabricating these little bracket things I want to make sure that they are entirely neccesary:

Borrowed the image from a fellow forum member.
Basically, its a bracket that spots to the inner sill and outer sill with a nut in it that is accessible through the hole in a genuine outer sill. It seems to me that all the bracket is for is for tooling when the car was originally made. Some people have said that the bracket adds strengh to the sill but I can't really see how when it's located so close to the end of the sill (where it is of course, welded already), now if it were in the middle of the space between sill end and jacking point I could understand.
So my question is, do people put these back in or is the general idea to chop them out once rusty and leave them out? There is one at each end of each sill, by the flitch and by the heel board.
I hope someone can answer this question for me, or at least give me their previous experiences in their restorations.
Thanks,
Adam
