Manifold vacuum tee *** help!!
Well I broke my manifold vacuum tee & need to find another. Anyone know the thread size on an Edelbrock RPM Air Gap manifold. The hole right behind the carb, on top of the runner. I need to find a new tee, any suggestions? I only require the trans vac modulator valve hose & one other port for the headlight doors, etc.

try Zip Corvette, not sure if these will fit but I believe 3/8 NPT as mentioned is a standard size...

Thanks Guys for the input. Zip nor Wilcox had anything in stock, I even tried different years & configurations. Actually one of them told me I was better off going to a plumbing store. YUK!! My trans modulator valve hard line comes in from the top of the fitting. It is a bit tight with a Holley but it worked. I broke the dang thing 
I dont think I can straighten out the trans hard line & re-bend it for a side exit fitting & of course nobody has a new different style hard line for sale. I'm in a pickle here. Unless I cut the tight bend off the hard line & make a new bend BUT my original line has a reduced tip, it goes from aprox. 3/16" to aprox. 1/8" where it enters the fitting. Why, I dont know?? Increased pressure??
