According to the Clarkes Tyre Rim and Wheel Service at Leichardt on the first page I can get a Twin manifold,extractors,lowering blocks,floor gear change,traction rods and an alloy rocker cover all for only $74.85 .
Might give 'em a ring and order 'em.........
.......... actually I might order a few sets of 'em 'cos you never know.................
there might come a day when these parts become rare,expensive and hard to get !!
