Seat Runner Assembly - missing lugs

I have just acquired a 1974 308 GT4 and am now in the process of restoring it to original. The previous owner had replaced the original front seats with a set of OMPs but luckily he did retain the originals, so i now have those. Problem is when the OMPs were installed he seems to have cut the vertical lugs off the seat runners to make the OMPs fit flush. So now my seat runners have no way to secure the original seats.

It also seems these original runners are no longer available.

Anyone had to do this before? Maybe i just need to have two new lugs created and welded to the runners.

 

Thanks will check it out!

 

Thanks for the kind offer but i had a local blacksmith weld some new lugs on for me and the seats are now in.
