Todd helm seats - refurbishment

[TwoHooter]

I need someone with experience of refurbishing Todd helm seats - not the upholstery, that's OK - but the rise and fall and fore/aft adjustment including the footrests. Not difficult, I just don't have the time. I spoke to Todd in the USA and they put me on to their UK distributor who just isn't interested. They passed me on to an upholsterer but I don't need upholstery. Any ideas?

Any decent mechanic should be able to do this work.
