Digital Camera Old Flash Adapter Home Made I Have A Sony Alpha 350 Dslr Camera, Will An Older Digital Flash And A Hot Shoe Adapter Work?

I have a sony alpha 350 dslr camera, will an older digital flash and a hot shoe adapter work? - digital camera old flash adapter home made

I have two older flashes. Automatic Vivitar 2600, and Sakar Auto 27B, therefore, only compatible with Nikon and Canon. If I have a Sony adapter for Nikon to use these flashes?
