Hi all, In a few days I might be coming up to fitting my outer sill, and I am a bit stuffed.

My dad says that I should place the sill under the top of the original, if that makes sense. So a tiny lip is inside the first and the replacement is underneath.

I said that i should butt weld it upto the original and weld along the original line, or just under it.

Here are the pics of the sill in question



All the inner and other stuff is welded now by the way, its just the outer I need to fit.

But what advice can you give me? Any tips?

What is the best way to about this?

I am using an after market Hadrian outer sill by the way. So I am unsure it it will be a perfect fit, but nothing a wee bit of filler won't cure I'm sure.

Any help greatly appreciated
