I am not sure how you got the information on the install of this motor. The Origin Live website has table listing what you need for the install on Thorens under fitting motors.. You were supposed to buy a tall pulley along with the motor kit. This would have eliminated the need for the billet. The instructions also tell you to use only one of the mounting points. This is how I mounted on the motor my Linn. There are several pictures on the web showing installs on Thorens. There was not one with the 126 though. I didn't see anything that would have prevented the mounting. I have no experience with modding the Thorens, just my own Linn. No link to Origin Live either, other than user. I do my own mechanical work on autos, house, etc., so I do have an insight on this stuff. Many decry the complication of setting the Linn suspension system, but it is much simpler than any car and was no problem for me. DIY can have many pitfalls, even for the experienced.
