Temp sending unit locations

I am installing Holley Sniper EFI on my '77 460 and need an additional coolant temp sending unit location. Any ideas?

The Sniper installation instructions advise against putting it there. I guess I will put it in the manifold ported vacuum switch location, I will just have to get an adapter because the opening is larger than a regular sender.

I feel silly for even asking the question, because the solution was so obvious and simple. Yes I removed the unused ported vacuum switch on my 460 located right beside the temp sending unit and it is the perfect spot for the Sniper (and FiTech) temp sensor. I thought that the threaded opening would be larger because the old switch took a larger socket, but the opening turned out to be the correct size. Yay!
