Seat Belt Part Needed

I am installing 3-point retractable belts in my '73 S and need a part that is NLA. The part number is 901.521.044.00 and is referred to by Porsche as a "Seat Belt Bracket". There is one mounted to each side of each seat, and I was able to obtain two new ones for the left hand side of each seat (the odd numbered 901.521.043.00) but need two of these, op-hand of the one pictured below, for the right hand side of the seats. I am ready to powder coat old ones if necessary so used and slightly less than perfect will do.

Any help is very much appreciated. Thanks.

I have a pair but the oblong holes have been opened up for larger bolts. Nothing crazy but you may want perfect.

I will email you some photos.
