Next job was to make the suspension bush assemblies. The "book" advises the use of metalastic bushes from a triumph herald or similar but i wanted something with more performance so i decided that polyurethane was the way forward.A full set of bushes, tubes, brackets and bolts can be bought locally for about $360 AUD but i wanted to manufacture them myself so i spent a lot of time researching poly bushes, their suppliers and prices and was surprised at the high prices but eventually found a suitable solution.

Surprisingly the closest bush i could find to the size i wanted is a set designed for steering rack mounts on an EA Ford Falcon. The only modification i had to make to these is to remove 2 mm from the shoulder of the bush and shorten the crush tube to fit within the brackets i had made.

The outer tube (eye) is ERW (electronic resistance welded) mild steel tube with OD (outside diameter of 34 mm. I had to machine these on my friend's lathe to A: remove the weld protruding inside, B: remove ovality C: create a smooth inner surface for the bush.Here we see machined eyes on the left and unmachined on the right.the finished eye. You can still see where the weld is inside the tube but it is smooth enough for mounting the bushes. A Day's work machining the eyes, crush tubes and bushes. Glad it's done and satisfied that i have made them myself. Total cost is about $120 including brackets which is a big saving from $360. Nice result!
