Hi guys

well i got my main brackets all powder coated, they look fantastic, but in my quest to secure all the parts for the spring upgrades, i came across something. When i got my new diagrams for the bolt patterns from GM they gave me a print out of the brackets, and i seem to be missing one. Its sorta triangular in shape and would go over the PS pump. I ve done intensive searches for this part and GM says its discontinued. I cant go check on thet car sinces its in cold storage outa town.
For those with the book, its Diagram MF06-016 #1 part

Any pictures of this part and/or area of the PS pump would greatly help confirming that this goes on a 1988 TPI 350, as most pumps ive seen come with the pulley directly on it.
Any place i could buy would be appreciated too
