Need some help with the Brinkmann Smoke N Grill Professional-Smoker mods

[waterjockey]

I have looked at several posts for the Brinkmann Smoke N Grill Professional-Smoker and was wondering if anyone can tell me what the fitting sizes are for the gas connection to the smoker burner any help would be appreciated

( I'm guessing they are  3/8" SAE Gas Flare )

but with most stuff from China not really sure

some of the guys who have made these mods might know I hope
