New upper came with brake on it but I bought a different one took original off and crush washer wasn't too tight, well put on new brake and crush washer and washer slid to one side so backed off to straighten retightened couldn't line up no matter how tight, washer deformed had to cut off (sweet). So another new washer and hand tight is just past center so I know won't go a full turn what do I do? Idk first time owner just received two days ago
