Yes. '67 Bisquet style.
Two pieces of angle iron welded into a box section. Installing the nut onto the bisquite mount was a PIA but it is anyway, so really not a big deal.
The box section to the k-frame mount was bolted together.
IIRC I did slightly grind back one of the original mounts on the K.
I still have the K, and maybe the box section too, if you want to get pics.
