Merry Christmas to me! I splurged and bought a Baby Bushwheell from Airframes Alaska. It’s the perfect mate for the T3 suspension. There is a sleeve that has to be press fit into the housing for the bolt. I guess it’s an area that may get some abuse so they give it a steel liner. Mine was just a hair too long. A couple of passes on the belt sander and it was just right. There is also a spacer provided for the suspension, but it was a close tolerance fit and wasn’t needed. I suspect it may be needed if you are mounting it to a spring.
