November 7, 2009 - After a certain amount of noise in the garage, I've finished the axle brackets for the lower trailing arms.
I gave my self multiple holes so I can play the geometry, but the second from the bottom is the one I'm planning to use.
Things are starting to come together on the suspension setup. The MG had a travel limiting strap, and the mounting bracket is well placed for the shock mounting and I can put the shock mount on the back of the lower trailing arm brackets. I'm not sure the upper will be strong enough so I'll probably reinforce the bracket. All this will give me enough room to comfortably run a shock with 5" of travel.
I'm also going to use the bumpstop mounted on the frame so I don't rely on the bumpstops on the shock, which will also take some hard impact loads off that bracket. It does mean I'll have a hard rubber bumpstop, and I'd prefer a softer setup. But I'll see what I can do about that down the road.
So, plan of attack. Build the mounting bracket for the upper link, then weld all the various brackets on the axle. That'll be fun - the center one will be welded to cast iron, which is not something I've done before. I also have to be careful not to warp the axle housing with the two lower brackets. Once I have the brackets on, I'll confirm the length of the arms and order the swaged tubes for the arms. Then I'll be able to move the suspension through its range of travel and figure out the best way to run the Panhard rod.
