On second thought, although some of my experiences with Mac's , --and their manufacturing side (Specialized & Cartouche) have been 'less than stellar' in the past, I will definitely give you the benefit of the doubt in this since you have come trying to be of assistance.
May I ask what your background is pertaining to Model-A restoration and/or repair of them? Why I am asking is, if I were to inquire as to what I would need to do to one of your 1928 steering wheels to make it fit correctly, is this something you would have first-hand knowledge on what I would need to do? Maybe the same question in other areas such as if I were to ask you about seat fabric for a 1930 Sport Coupe, --and more specifically how close is it to original material, is this something you could help me answer accurately? Thanks, and welcome to Fordbarn!
