Getting down to the chassis is something of a milestone at which point the whole vehicle starts to look more like a project. The preceding days I had wire brushed the fixings I could reach easily and applied some household Water Dispersant and amazingly all but 2 fixings on the rear cross member tub brackets come off with no fuss. These fixings will be replaced with matching stainless items during the rebuild.
For some reason I took no record of the seat box coming out but it will need a lot of work before it’s refitted. The tool / battery tray being made of steel has rotted beyond practical repair (for me at least) and there’s a lot of bi-metallic corrosion where it’s fixed to the aluminium seat box. I’ll post some pictures when I get round to repairing it.
