86-88 Radiator cap assembly question
I am going to buy a 86-88 cap assembly w/ overflow tube to eliminate AST.

Which cap does it come with (pressure or flat) and which one do I need?

yeah, the mazdra trix filler neck comes with the cap
you can also get a cap for any FD from your local autoparts store, they should all come with a 16lbs spring cap stock

I just wasn't sure because the one I have is w/o overflow tube has flat cap.

You have a 2-piece coolant fill neck right? ie has a pair of 10mm head M6 bolts.
You're deleting the AST (which has a pressurized cap), this is why the S4 piece comes with it's own pressurized cap. With a non-pressure cap your boiling point would be too low.
