[DeTomaso] Clutch Slave Repair Kit

[threemacs at aol.com]

I am having a very difficult time trying to purchase a clutch slave 
repair kit for my 74 Pantera.
 From the information I have gathered it is a "Beck/Arnley Part # 
071-3438".  The auto supply houses I have called are not able to match 
numbers.  I have called Beck/Arnley but they won't sell to individuals. 
Does any one know where I can get the kit?
