Hi everyone, I'm looking at buying a used Gitzo locally but it doesn't come with the centre plate (see photos below). This is a Gitzo Systematic 3542LS which seems like a great model and the used price is a good deal. I'm hoping to replace my much more entry level Manfrotto with it, to get better stability and easier setup/takedown. Unfortunately, it doesn't come with the top mounting plate piece that a new one sells with. If it doesn't affect use I'd like to buy it, but not if it's crucial. So maybe a Gitzo owner can chime in if they know?? (cross posting this from Rangefinderforums in hopes of getting an answer before it's gone)
Do I need this piece to attach a tripod head to or no? If I don't have it, what will I miss out on that I might not be aware of? I'm worried there's something I'm not thinking of besides the bag hook, or that it totally won't work without this plate. Basically, if I buy this would I then have to replace that missing piece ($100 or so) or can I do fine without it?
Here's the image of the tripod legs I'm considering, without the piece:
And here are a couple of shots of the "normal" look when the piece is in place:
Finally here's a picture of the replacement piece (I think that's it anyway) from B&H Photo:
