2nd gen battery tray question

Question for everyone who has changed to the 2nd gen tray and installed the group 27 battery. Working on a mod to be disclosed at a later date and need to know if the rear of the battery moves back any whenthe new tray is installed? I know it's the same width but are the mounting holes the same so the relative location of the tray doesn't move? Any info now would save me some work later. Thanks all.

 

i just installed a group 27 in a group 24 tray.
i shaved off the lip off both sides of the tray and it fit right in.

 

Awesome. Gives my next project the green light.
