Dropped hangers to suit 1979 Chev C20

[bb1979]

BACKGROUND INFO

I have a 1979 Chev C20 Pickup (long wheelbase, 8 stud single wheel diff etc) I think also referred to as a 3/4t pickup over there. I am in the process of doing it up, body and paint, interior, lowering, big block conversion.

Though a supplier of Chev parts here in Australia I have purchased a set of dropped hangers and shackles to suit. After waiting 6 months to get them from their American supplier they don't fit. After numerous phone calls and emails between myself and my supplier here in Australia, we have come to the conclusion that they are to suit a C30 chassis (dual wheel flat bed). I have now been told that the hangers on my truck are going to have to be custom fabricated and that the American Supplier has never seen a hanger which matches this application.

QUESTION

Can anybody identify this hanger. I have also done a rough sketch with dimensions. Sorry for the crappy photos. I am thinking that it may even be from a different year model or something. But I am positive that this must fit a chevy chassis. I am getting very frustrated at the moment I would have done a home made flip kit and notch if I could of but the registration authorities frown on it and I don't need the hassles.

Thanks

I can't ID those hangers, but here's a bump to get you back on top...
