Have you had a look at these people? Rakeway motorsport
Especially their 'crossbreed' wheel spacers Crossbreeds
There's a Toyota to Land Rover listed, so they might be the ones you want. D'you know what stud pattern he's looking for?
Edit - you say he wants a Toyota 6 stud and the ones illustrated have 5. Contact Rakeway and I'm sure they'll make some up.
so you recommend getting lr hubs(and brakes) re machining to fit lc stub axle bearings making a bespoke drive flange to match lc drive shaft to lr hub is easier
