Carrier suspension rods

[Lynn Eades]

My guess is that all three are dimensionally the same, and so interchangeable, assuming you have the appropriate nuts for them. I sent a suspension spring to a T 16 owner in the U.K. and it proved to be the same as a MkI U.C. spring.
The Australian rods are the same as the British and Canadian ones.
The difference being the BSW thread on the British and Canadian ones, while the Australian (and I suspect the T16) employs a UNF thread
It has occured to me that I should have said British thread form and American thread form (The Aust. ones might be UNC)
