Hi Dutch. Regarding the front sheet metal question - it's all hung from the rad support and the firewall. There aren't any connections to the frame at all, at least not on my 48. This is my first AD build and I put mine back on the original, albeit heavily modified frame. I didn't make any changes to any of the cab, box or sheet metal mountings. If I look back in my thread I might find some pictures that may help? Joedoh has done so many that he can probably offer more information.
