Bumper bolt size?

Anyone know the size/pitch of the 2 lower horizontal bolt into the frame are for aftermarket bumpers? I know the front 4 are M10x1.25. Looks like the other 2 might be M12x1.25? Found a hybrid/ low profile style bumper on Marketplace and it didn't come with hardware. I needed longer bolts for the front but I have the factory ones to check with. No idea on the other two, and I might have to order them because everything locally has a really long unthreaded throat.

I know some pre facelift folks will love to hear this, I bolted an older LFD GX bumper right up to my 13. I couldn't find a single photo or testimony of anyone else having done that. I have a Limited but with the 10 to 13 Trail bumpers. I needed to space it out 1/2 inch and it ended up working out great. I'll post photos and details on another thread.

 

Please do. I would really like to see this. I've been looking for bumper options for the Limited for a while.

 

Is it just that I don't see it myself, or is there a reason why I don't see this thread when I look in the 5th gen section where I posted it?
