Chassis suffering from the usual rot so out with the old.
Under passenger seat base had been repaired in the past without removal of the OG section, and the gap packed with filler & newspaper. So patch just rotted out. All weak metal cut out and new section welded in.
Redunent holes in the seat backs welded up, floor fully welded in place with heater duct & table mounts going in. Nose cone panel welded in & all joints seam sealed both sides.
New chassis & floor given a good shultz protection. Insulated heater hose fitted. Servo vac' line & remote cooler re-installed.
Etch primer inside and out.
Quick blow over to stop the moisture getting to the new metal.
