I just purchased a 92 325 conv. but the power top is not working? There is a piece that is broken under the package tray looks like it is the rod that would lift the cover. The top would retract until the cover had to lift and then it stops. I popped the motors down to let the top down now the motors won`t run. Does any one know how to synchronize the motors and get them working. I will replace the rod that is broken and hopefully get the top working
