I used some black electrical tape to hold the bracket in place. I tried zip ties and just couldn't get them situated right. Once I was ready to finish tightening everything up I just pulled the tape out. I did enlist my wife's help who is only 5'4" and was able to get both arms in there...
Once I heard that Mojito! wasn't going to be around for the 2019s we had to pull the trigger. Had it home three days and already debranded, blacked out the logos and added the stubby antenna. So many more things planned, but need to pace myself. Loving every minute in this thing so far!
