Stahl Or Other 1 3/8" Headers For Automatic?

[Stanley]

After seeing ProFab's number on a recent thread in this forum (and getting the same no-answer) thought I'd better ask before spending much time trying to find them (the headers). So, did the Stahl 1 3/8" headers fit a 240Z with AT?

 

Or, is there another source (other than OZ or Japan, expect RHD headers won't fit around the brake and steering stuff) I should try?  Running 1980-81 small port head on stock '73 block, figure 1 3/8" primaries would give best mid-range torque and maybe extend top end a bit.
