JC's seat covers are made by someone in his area (at least that was the case 2 years ago when his upholstery supplier made me a full set for my 1954 Chevrolet Suburban). I think that person has been supplying upholstery sets to JC for many years. The upholster was very nice to work with.

The set I had originally bought from JC (in 2003) was the wrong color-combination for a 1954 Suburban - it was a 1953 set (all maroon), which is different from the 1947-52 color and the 1954-55st colors (maroon & gray).

Also, the set he sold me in 2003 did not fit the spring dimensions in my Suburban. I seems the sizes of the cushions/springs changed some time between 1947 and 1954. JC (kindly) let me talk with his seamstress regarding making a correct set of patterns for my seats (and the correct colors). I ordered through JC and paid JC.

The set I have now are beautiful in fit and appearance (I had original covers to compare-to for some cushions).

Note: JC's installation kit does not contain matching numbers & types of layers of "cushioning" material. His kits do not provide sufficient padding.
