A little progress. The rear axle mocked up and waiting for fab parts...
I found these on eBay. Pair of Shockwave 9000s.
These are from Ruffstuff Specialties and I bought through Krawltex. The heims came with the jam nuts, tube inserts and misalignment spacers and the frame brackets are adjustable and threaded. These brackets will be used on the inner frame rail (after I box it) for the upper rear links.
