Yes Doug my XD - XF door latches held in place, so I can at least recommend them!
These are double strike and legal. The seat belts help too!!
Not sure in the scheme of things though if a smaller version could be sourced off another vehicle. I'm guessing they'll all be pretty similar in size unless you warp back in time to say Marina latches as suggested in the GF build booklet!!
These are huge I gather.
Happy building!
Cheers
