Sard/HRF Manifold wastegate flange

[fussman]

I Know the original wastegate for this manifold is the Sard type-CII.
what other wastegates will bolt on? the Tial F41 'looks' the closest.
can anyone confirm other compatibilities ?

The sard wastegate is a 38mm, and the Tial f41 is a 41mm wg,

Also if i remember correctly, the sard wastegate is a square type flange, not a vband?

Tial a square flange also.
