I meant to ask why you moved away from the stock split diff mount with ERC motor mount? I think you said the mount screws kept backing out on you? Are you using a good grade of thread locker, not liquid but the gel type from your local auto-parts supplier?

This stuff is great as it does not require a long curing process like conventional liquid thread lockers. Also, you can use CA glue for the plastic side of the mount in a pinch. You could even go up to 4x14mm mounting hardware on the plastic side to give a bit more bite. I can honestly say that I've never had my center mount screws back on the plastic side of the mount.
