Relocate coils on ls swap?

[Slowguy]

I am getting the stock truck harness rewired. I shipped it off a while ago. I think he’ll oretty much do anything I like but this got me wondering. I suppose this might be a fairly specific audience but I’d like to ask anyway. For those that have swapped in an ls, AND relocated the coils, AND (this may not matter) have a turbo manifold on the pass side, can you recommend where or how to relocate the coils while I have time to get the wire harness set now? I was thinking possibly the top side of the frame rail on each side?
