Started to take the sill's down to bare metal as when lo@der had this he noticed a rust patch on the nearside sill.And as i have two new sill decided to see if it was that bad to fit these but to my surprise i can't belive how solid this shell is i did read on post be4 i got it that it was very clean.Im going to weld in a peice of a sill but only where the hole is as shown in pic as it solid the rest ot the way.
