I can't convert the PDF to a jpg and the file is too large to post, so I'll email it to you, Allan.
The file is for the larger of the repair parts. It's more involved than the smaller version. Basically, you want to measure up 20mm from the bottom the rail and make a horizontal cut the same length as the base of the smaller cradle nut repair piece. Then cut upward from each end for a distance of 50mm. You can then chisle the old nut loose and the repair piece will easily insert into the frame rail. As I poreviously said, there's no need to weld the cradle nut in place. It won't spin within the frame rail. Also by not welding it, it will easily align with the cradle bolt when you insert it.
If anyone can convert a PDF to a jpg file, let me know and we'll post the conversion here.
