Thank you for your order
We do not have such a socket, but the leads are very robust on that bridge. You could run it thru a small piece of perf board, or mount it to a heat sink. I would tend to use 4x the Stealth 4A/600VDC. Take a 1" square piece of perf, and drill a mounting hole thru the center. Mount it on a stand off... Mount your four diodes along the four sides of the board, and bring your four wires in on the four corners.
And yes, you can spread the leads on the diodes. Here is a really bad pic I blew up. I just happen to have it.
