Clutch pedal to transmission linkage bracket question

[Lemurskin73]

Hello group. I need help locating the proper engine side bracket that allows the pedal to throw out bearing arm linkage to pivot. I have an original 67 gmc that came with a 305 v6 and 4 speed. I replaced the 305 with a 250 about 10 years ago and was able to make a bracket that attached to the side of the 250 block. I'm in the process of replacing the 250 with a 292 and noticed that attachment point is not on the 292 block. Is there a bracket part number for my application or do I need an entirely new linkage? Thanks in advance.
