I thought it best to put the final stage in the diff cage up now the fabrication is complete.
The cage had the lower mounts cut off so I could make new thicker ones. Where the first ones were bent pieces of steel, the second versions have bee cut from 2mm thick 40mm box section. This makes them much easier to build as well as being stronger and thicker. Being wider, they will require washers inside them to prevent any crushing, but it also means that I can alter the positioning of the legs slightly too.
with everything bolted in place, the diff was levelled out as it was hanging tail down a touch. This did open a small gap between the legs and the mounts, but nothing wide enough to worry about with MIG welding. And so it was tacked in place on the shell before welding fully on the bench.
So the diff cage was finally completed. With the diff now in it's final place I could refit all the suspension to check for clearance. Before the diff was levelled there was a small gap. With it levelled and bolted in tight, there was no longer any gap.
So the final step in fitting the diff is to cut the cooling fins down a touch to create some space. I had expected to shave a little off the outer fins to clear the A frame link, but it looks like I'll be trimming them all back.
