The chassis backbone is attached to the triggergaurd by a button head screw in front and the action screw in back.
Unfortunately the T1x mag housing bolts to the action with a rather large metric shcs. (See my post a few pages back for pictures) You will have to reengineer the front triggergaurd attachment as you have to mill through hole for the button head to provide clearance for the shcs. I trimmed the head of the shcs on a lathe to minimize the amount of material removed but still cut all the way through the centersection of backbone and down into the triggergaurd.To allow the mag to seat the front of the triggergaurd will have to be milled to allow for the basepad as the mag seats.
@Massoud did a really good job of skeletonizing the triggergaurd so plan your front attachment well, there isn't a lot of extra "meat" a traditional solid xlr/mdt/mcree would be a lot easier to modify probably
