Where I can find SFX begin data?

[Borneq]

I wanna list files from ACE archive. I found that for .ace file I need  go to to 0x35 byte and read structure:
    fill0 - unknown for me, 7 bytes
    packedSize - 4 bytes
    size - 4 bytes
    dosDateTime - 4 bytes
    fill1 - unknown for me, 14 bytes
    textLen - 2 bytes
    text - textLen bytes
But how found data from sfx exe files? their size is about 70 KB. I read PE header but I can't found where begin data.

The archive is coming just after the SFX stub. If you wish to see, here is a small project :
