Does anyone know of a source for the inner door frames required to upholster the doors on a MKIII? The fabric is secured to the frames then screwed to the inside of the door. The supplier I'm working with quoted 3 weeks to complete but I just found out they are out of stock and want $700.00 for air freight from South Africa or sea freight which is 8 weeks + installation time. The frames are only around $100.00. I shipped the doors and seats to California from Minnesota a couple weeks ago hoping to have them upholstered and be back by June 1st. I'd like to have them back before the snow fly's. Thanks in advance to anyone that can help. Greatly appreciated.
