For your A2, I think you will find that you can easily install the X Door hinges to the B Pillar, but may have to install Rivnuts on the A Pillar area, because those holes might be messed up from the MAK Armor attachment. The Strikers on the B Pillar will be easy. Just use the upper two bolts that hold the blocks to the B Pillar for mounting, but the rears may be a bit of a challenge as the MAK Door Strikers required drilling out different and larger holes. Door hinges need adjustment for each Humvee usually, because of variances in assembly. You want an even line across the bottom for sure, but you don't want it so tight that the seal gets pinched and bulges out. After you have that figured out you can place the strikers for the rear doors and see what you have to do. For the front doors, if you install rivnuts for mounting them, make sure that they are aligned or your door will bind when you open and close it and the hinges on the doors will constantly come loose.
