There is one off buford hwy almost to doracville. I think it's called doraville driveline. You can call 4wheel parts on buford hwy.. they'll know them. I think they use them for their stuff. 4wheel parts number is 770-840-0365.
I know this cause I might be using them for a dual transfer case setup in my 4runner. And I'll need to modify my driveshafts. Good luck.
