Early A (65 Dart) Pre 67 Seat Brackets

Ok The riser portions like the one pictured above I dont have.
The glide assemblies with elongated holes that bolt to those risers I do have 4 of. The chrome knobs are missing from release levers but the springs, rollers, etc.. all present.
These really wont help unless you find the 4 riser portions needed and those are often rusted away. You might consider fabricating those portions too.
Just trying to help . Good luck
