...the controlled orifice fitting on top of the 76 turbo anyone know what size it is ?...or where to get a 90 degree fitting that will fit the turbo luber -4 an line...guess it would be a -4 female to male -4 90 degree fitting in order to make the turbo luber line go in the right direction...any ideas for this?...thanks noah.

If it's a dual ball bearing 6776, then it uses a specific tapered flare fitting. Not sure on the thread, but they are supposed to come with a specific restrictor fitting that accepts a -4 AN line when purchased from PTE.
ATP Turbo makes the restrictor fitting as well.
Oil inlet fitting for GT28/30/35R with built-in restrictor: atpturbo.com


If it's a regular journal bearing 6776 turbo, then I believe it takes a 1/8" NPT to -4AN male style fitting.

You might have to notch your sheild like I did for the oil line. Look at post #11 for a pic of my engine bay on this turbo section. Thread is "6776bb turbo and stock location PTE IC"
