A mock rear a-arm was printed today so see if everything fits. Their are a few small changes I need to make with the spacing and sizes of the holes but for the most part it turned out great. The finish surface isn't the smoothest in some spots but with a slight amount of sanding it became smooth. I'm also think I will make the center section of the a-arm thicker since I don't think its quiet wide enough.
I'm going to get a final drawing done of the rear a-arms and get the front a-arm design ready for printing too. A nice feature about the a-arms are they can be used on either the right or left so I don't have to have as many spares.
