73-87 250 to 292 swap, engine mount question

[TheOcho]

I'm swapping out my 250 for a 292 in my 1978 C10. I've been searching and searching for a photographs of the correct, passenger's side, engine mount and brackets. I've come up with nothing. There are hundreds of pics of 292s in pre-1973s, and I've seen a few of 292s in 73-87 K-Series, but I've come up blank on pics of the 292 in a 73-87 C-Series. I'm sure I'll have to fab up my own mounts or modify something else to work, but I want it to look as close to factory as possible. Does anybody have a factory 292 in a 73-87 C-Series? Photographs would be greatly appreciated. Thanks in advance.
