I had the same issue when I bought my t56....I found an exploded diagram that had all parts listed, then googled the actual spacer and found somebody selling them for pretty cheap.  
I looked again today, but could not find the store I purchased mine from.  I did find this guy on protourig.com
"The bracket is called a clutch cylinder actuator bracket, i can make as many as you need. parts,time,and material cost $129.95 plus $10.00 standard shipping and delivery. you can contact me at
