I took photos and posted them up. They should be in that thread. I took and posted lots of good photos, as I am a professional commercial photographer.
As far as buying bulk marine carpet, I would guess that if you are going to go that route, you could not be very particular about the fit, because to get the carpet to fit right, it has to have a lot of cuts and a lot of seams made at angles that I think are very difficult for an amateur to do. If you buy bulk, flat carpet, don't think that all you have to do is cut the shapes, sizes and holes. Sometimes the carpet needs help to mold to abrupt angles. And that can only be done by either molding the carpet, or cutting it and re-sewing it at an angle so that it forms a change in direction (from horizontal to vertical). Molded carpet would be ideal, but some molded carpet is actually not as good as the aforementioned "cut and sewn" carpet. Why? Because the molding process can be poorly done, and can cause abnormal stretching.
There are quality aftermarket molded carpet makers out there, but they don't want to bother with the small number of old Land Cruiser owners. So we are stuck with those who do.
I will say this about Chestor and Herrod. They are good people who care about your happiness, and if you are not happy they will send out something else.
