Tee Nee Trailer ?

I've got a Tee Nee trailer - probably mid 80's ?  Although it's in good shape - it's needed some love.  I fixed it all.  BUT, I need to buy fender brackets ( you would think this would be simple ) - but alas, they seem to be specific.
Anyone ' been there done that ' ?  They are about 8" total length ( a pair per side ) and have a hole on each end.  The bend is specific and what I've found at Waste Marine and online does not seem like it would work.
Unless I get som einsight, my next next stop is to a metal fabricator...
