Over on the AACA forums someone had a Lebaron-Bonney Buick kit in which part of the fabric was a bad dye lot and faded from brown to green, in the box IIRC. It stretched out from January to October while the replacement fabric was ordered (and LB was waiting for it). I am not sure if it ever came, or if it did and was also defective. The Buick owner eventually had to use different fabric.
Thread is here, trouble starts on page 45, post 1124:

If you go through a few pages you will see pictures of the fabric that faded to green next to the brown.
If LB thinks there is a big enough problem with the fabric you need that they wont sell it, I would tend to believe them.
