Looks like you got most of your questions answered and that is good - in the first photo of the sub frame, the tab at the back of the cross member ( with the bolt head showing ) is where the glove box mounts - nice feature to have.
The lift bar - used to get the bike on the centre stand- is also located differently also. Not so much leverage on the B model being more to the center of the bike - no doubt to accommodate the saddle bags.
