The one I got from Brand's has the wrong curvature in the center section and the two end pieces are tilted back instead of being vertical which would create a crease in the top material. Lastly they end abruptly without the small sections that insert into the pockets on top of the quarter panels which serve as the attachment for the welting finish tips. Rectifying those shortcomings has been more than minor fitting, which would normally be expected.
Charles,
Sorry, but I am unaware of a source that i could recommend. Perhaps someone who knows of one will help both of us by sharing their experience.
