Well looks like I need to make my own. Just heard from my Nacra dealer and nobody in the US has this part - he has to order it from Nacra EU for the reasonable price of ... $41.50!
I'll be hitting up Skycraft later to get the aluminum strip.
Think I might be able to JB Weld the bolts into the backing strip?
As northsea pointed out, the fact that they are welded is just for ease of installation. There's no benefit to welding it. Make a stainless plate with holes and bolt the bolts through it.
