You can pretty easily machine bushings for the CQ.  It's just a round 
barrel with a flange.....   Of course, this assumes you have access to 
this sort of equipement and I'm rather surprised you can't just buy new 

One neat trick is to burn them out with propane torch.  Messy and 
smelly, but very effective.  BTDT on other cars.
