Agreed, only thing that varied bike-bike were the spacing requirements. I know it drove Ohlin USA nuts to deal with this. Variance solved with SS washers, easy.
Funny I did the same thing. No problem at all. Shame they pulled the plug as the shocks are great on the Morgan. I though they were off the shelf shocks made for other motorcycles to begin with?
Ken, that's my understanding too - off the shelf from other bikes. I don't 'think' there's anything custom except the spacers, which is a non-issue.
Hopefully, there's a CocoMats' analogy here, in that they also prefer 'square pegs' and tire of dealing with non-precise/returned 3W fitments. But if you template yourself, no problem.
