Finished up today, well almost. Still waiting on a Deutsch DTM 6Pin DTM06-6S DTM04-6P for the ML-ACR so it's completely clean. I had to do a little modification for the Shrockworks tray and upped the rivets to 5/32 to compensate for the loss of the stock battery tray "pins" to body holds (see photo).
