In this view you can the expander and adjuster parts in the plastic bag at top. They are in top shape.
Over the past few days have also started to install the springs on the chassis, seeing as the axles are coming together and it may be possible to make a rolling chassis fairly soon. Today I found a place that will remove the old tires from the wheels, and have already lined up a company that will media blast the wheels. Then the wheels can be painted in Limestone (the original off-white visible on one of the wheels immediately behind the chassis) and the new tires installed.
The original rear springs bolts are truly seized, and I can't get a good angle to try and get them off, so have ordered new ones (plus shackles) from 3 Brothers Classic Rovers. Was able to use the original shackles and shackle bolts on the front springs.
