Several companies make Alu knuckles- are you looking for 3.3spec ones? If you search ebay for 'e-maxx', you shoud find the RCRaven plastic body posts that are round, but they have seriously high shipping charges (it might be worth looking on the crawler websites for round body posts as thats what they use 99% of the time- just trim to the desired length). I use stock pivot balls and they are fine, nothing much to gain I dont think except a small weight saving.
