OK, I dug back through my emails to jog my memory.
I had a tandem from ~97/98 with old black freewheels. (I don't know if they were ACS but they were definitely original to the tandem) They were totally worn out and grinding. I chose to upgrade to the white industry freewheels. However the white industry freewheels have a hard stop on the inside of them. (picture below) The original freewheels were basically passthrough - completely threaded and you could just spin fully on up to the outside intermediate shaft hard stop to lock them. The white freewheels had to be installed from each side - one installed on the inside and one installed on the outside. This required a special/different intermediate shaft that I got from Todd. My lesson was that it is cheaper and easier to stick with the same type of freewheel. =)
