well good new, i called and left another message, afew hours latter the owner of matrix call me back

( i wonder if he reads here?)
we did some investigating and figured out the two front holes were about 1mm off and that wasn't letting the screws sit down all the way on the chassis.
he was very cool on the phone and truely sounded sorry for not getting back to me sooner.We talked about the production and he said i was the first person who has had this problem and that he was sending a new chassis UPS 3day and he was going to test fit it just to make sure i didnt get another odd ball
i also got pics of the of their brushless conversion comeing out
