MG mount for a M38A1 CDN2

[BOBM35A2]

I am trying to obtain all the parts to accurately restore my 67 M38A1 CDN2.
I am presently looking for the Machine Gun swing arm mount that attaches to the right side of the jeep. I have been looking for a while. I am prepared to make one if I had the dimentions and knew what the inside of the lower arm was like. If anyone knows where I can get one or send me close ups and dimentions of one, I would appreciate it.
Thank You
Bob
