I'm new to papercrete and have not built a mixer yet, but I've done metal fabrication for 20+ years. Yes, you will have to remove the shocks and springs. Obviously people have built and used these mixers successfully by just cutting a hole in the bottom of tank and lots of sealer where the diff pokes thru. I would fab up some bearing plates and use 2 flanged sealed bearings, sealing would not be an issue at all, then use a flex coupler between shaft and diff. Tank will need to be fully supported, and a rigid trailer frame would keep flexing to a minimum. You will need access to a shop with metal cutting abilities and welding equipment, someone that knows what they are doing helps.
