My understanding is there are two parts; the brass rudder tube/nut kit (bottom picture in Mystery's post 1/17/19 above) and the plastic bushing kit #61140 (middle picture in Mystery's post 1/17/19). The plastic bushing kit goes inside the rudder tube kit. My understanding is that these two parts are the original design and have not been changed/improved/upgraded. Mystery, here's where I'm confused, is there another rendition/part or upgrade that is different from what you've got pictured and what I currently have? Hope this is clear! Thank you very much for your help on this! Fred
All I know is on some ST44 I heard the tubes were plastic. The new design is metal. I dont know if the ST42 uses the same. My kit is still for sales. 2 for the price of 1.
