There are several companies online that offer seats for a 1949 Ford, including Mac's Antique Auto Parts and LeBaron Bonney. Choosing the proper company depends on an individual's budget and skill.
Mac's Antique Auto Parts offers one of the least expensive options for seats. However, this company is for customers skilled in restoring classic cars. While the pricing is very competitive, customers buy the individual frames, springs, fabrics and accessories to rebuild the seats themselves.
By contrast, LeBaron Bonney offers a more expensive solution for which it custom crafts and installs the seats on behalf of customers. While it also offers parts for customers, LeBaron Bonney's specialty is handling custom builds and installations either in-house or through its network of authorized installers.
