Just to wind this thread up:
The pictures hosted on my website are one's I saved when the thread was active. The member's name who built the mid-controls and posted the pictures and a nice "how-I-did it" was "Blues40." I've had no luck with my only couple of attempts to contact.
In the end he said that his wife had changed her mind and wanted to go back and get the Sportster she had checked out. He removed his control conversion from the S40 to sell it in stock form. Then he offered the controls for sale here on the marketplace. He didn't mention a price, but he only recommended them for lightweight riders, as I guess they had some flex in them if you stood up on them. I contacted him about buying them; but maybe he was afraid of liability issues; because he not only removed the post having them for sale, but he also removed the whole thread about building them altogether!!! I didn't save the text part of his post, so now all that remains is the pictures that I saved. I think his build was good, and the workmanship looked excellent; but perhaps they could have been made of stronger material or something.
Anyways, he proved it can be done, but he did comment that he wouldn't want to go through all the trouble again for love nor money or something to that effect!
As I recall, he also commented about the short seat height of the Savage making the new pegs mighty close to you; so long legs were really doubled up to reach back under your bottom!
