This question is for those of you that have replaced the cradle on your
conversion and used the stock "Y" piece.
I am trying to clean out the old tubing from the "Y" and the frame.  So far I
have tried a cut off wheel and a flap wheel on a grinder, a die grinder with a
carbide bit and a end mill with various bits.  Everything I have tried is very
time consuming and the results are not that great.  I'm not a machinist, so 
I only have rudimentary knowledge and skill in this area
I've been told this is a simple procedure.  Am I missing something, Is 
there a simple way to do this? 
Any help would be appreciated.
