Wow 55 pounds is pretty beefy, I agree with Manuallabor, go with some extrusion, either 1X2 or if you like the shape if the bosch extrusion you could go with a 1X2. Although this might require you to build in some cross bracings. I know that bosch stuff is pretty solid.

Are you planning on using the old andymark transmissions or just waiting on build season to order some super shifters?

On a side note, I was able to shift both of our transmissions last year using only 1 of the pistons with an extender build on. I can include some pics if you're interested. Although our transmissions were modified to be thinner, and thus lighter, I do not know if you can do it with an unmodified set, but might be interesting to look into anyways.
