Re: 56 Rear Torque Arm Bushiongs

Having just replaced all bushes on the arms of my '56 Patrician, there's a couple of tips in this topic I wasn't aware of at the time but would have seriously considered had I known. They are using '55 bushes and inserting a piece of rubber between bushes (size not stated). Anyway the job's done now so there's nothing to worry about for now, but for how long?
By the way, in disassembling everything I noticed the lower bushes were worn much more than the uppers. I've attached a couple of pics of the RHS bushes as these were replaced by the previous owner not long before I bought the car (I've had it for about 7 years). The LHS wasn't done by him as it apparently didn't need newies, but having a hell of a job disassembling that side makes me think they surely did need doing back then. Anyway, these RHS bushes have Packard numbers moulded into them, no mention of Steele, which could mean they were NOS.
If polyurethane bushes are suitable I'd consider redoing the job some time in the near future if it meant not having to do it again for a looong time. With my limited knowledge of the compression stresses on rubber bushes, my only concern is whether polyurethane would perform the same job (ie, compression v hardness). I'm thinking they would work well on the fronts as they seem to have a mostly rotation role, even though they are compressed during assembly.
I would also be interested in finding out more about the rear stabiliser bar (watts linkage) polyurethane bushes as the rubber ones I installed a few years ago are already showing signs of wear (the outer ones - not sure about the inners).
