8V aluminum intake. I figure I should replace the press in nipple as a precaution, I have the intake off anyway and the nipple looks like its probably the original.
Dearborn Classics sells a press in, Mustangs Unlimited has one that requires tapping the intake 3/8NPT. No mention if they are stainlees(I assume not).
Anybody been down this road? Ever try to fab your own?
