[Healeys] Syncro problem

There are a couple of syncros available and one of them is total  
crap. I had one years ago on a restoration that the car never got the  
body installed and the syncros started going bad.
So my bet is you installed the less expensive syncros that run about  
$120.00 a set and not the ones that are $320.00 a set of three.
