The hole pattern is the same....even up to today's model. Save the $$ and just buy a new one and use the bar and screws from it. No reason to plunk down a ton of $$ on something vintage that only half would be used anyway.

Thanks so much!

I wanted to post this in case someone else benefits. I swapped out a part from another drum and it fitted all right. But that is not the interesting bit (to me).

This Supra had really bad snare buzz. I was forced to tie the strings through the screw holes (since I was missing the bar) which certainly seemed ok, except for the knot part. However, I would never have thought that clamping the strings, such a minor adjustment, would make such a huge difference. But it did! Which shows me that the engineering in these great old drums was really quite remarkable. It sounds much better, because of a part worth a pittance.
