[DeTomaso] gumball pantera needs to remove a rear ZF stud

[LEVITT1946 at aol.com]

Dear Friends ,
 
My reverse issues that I have been having for months is possibly caused by  
a reversed stud at the rear of the ZF case. When my car was being restored 
I  asked the shop to install Chrome acorn nuts as a finishing touch on the 
back of  the ZF .
 
After speaking with Lloyd Butfoy at RBT he asked me if anyone had  reversed 
the stud so that less threads faced outside and the acorn nut could fit  
tightly. He said that if someone reversed the stud it is possible the threads  
are protruding into the inside of the case and when I try to go into 
reverse the  stud is hitting. I said I did not know but now that I think about it, 
the  only thing changed on the trans are the acorn nuts. The restorer 
doesn't  remember his name let alone the nuts. 
 
My dilema is ....How the hell do you get the stud out without killing the  
threads?  I really need to take it out to check. 
 
Any and all help is appreciated .
 
 
Thanks ,
