ST170 Double Sill Replacement

[aaron_2000]

After the ST170 thread, I decided it was time to give mine attention again. I need the rear drivers side sill repairing due to Forditus, the passenger side was done in 2016 (I assume poorly). I figured if I need the repair doing, surely it would be smarter to cut both sills and replace them with galvanised sills? Just wondering what the cost of the repair might be and the sill replacement option could cost? Wants a small sport weld to the passenger wing too. I also notice the passenger side chassis leg is damaged, pushed about 7cm back so the front bumper shakes, not got a pic but any idea of the repair costs for that too?
