Am in the middle of moving house at the mo.But i would only be prepared to get the underside back to bare metal,bag sealer it and then paint it.I would n,t want to be stripping then fitting all the old cruddy brackets, bolts and suspension back on.

Have a go your self.The hardest part for me was stripping it down and getting everything powdercoated and clean before i fitted it back on.It,s pointless sealing and painting the underside,then fitting all the rusty parts back on.They will need powdercoating or stripping and painted.
If you could your car to me on a trailer with all the underside stripped except the shocks,arms and wheels so you can still move it ,then yes i would do it for ya.
