Automatic Swing Gate... Need help / advice on installing (pics included)

[StartX Philippines]

Could someone guide me installing this auto swing gate motor, the motor will get bump on the wall on the current status of my attachment....

Should I try to weld and elevate the gate mounting to align on the wall height?

...Here we go,a right old long-distance survey...

Distance "B" is already achieved by the depth of your reveal,so you may need to modify the supplied bracket,and bring the pivot close to the fixing point.

An amount of trial and error,will be needed,so it can swing long-time baby

base on the measurement I post, do I need to cut the "GATE ATTACHMENT (GATE ATTACHMENT BRACKET" and make it longer?
