Need a cold shoe mount

so I currently have a wisner technical 4x5. It has no accessory or cold shoe mount. Any ideas on how to add one? Preferably non invasive. If there is something I can attach to the tripod that would be better. I will be mounting my wireless trigger on it. Thank you.

You might try B&H. A quick search turned up 204 possibilities.
