This little poly mount project is turning out to be a real pain. I got the driver's side done and all bolted up. I have all the bolts on the passenger side off and have jacked the motor as high as it can go, but I can't get the mount out. The metal "keepers" on either side of the mount are hitting the main bracket that goes over the mount. I can move the mount around, just can't get it out from the bracket. Any trick here guys??? What am I missing???
