Mort is an expert restoring Birds. His hobby not his business. However, he restores seat parts. Recently I searched for restored power driver seat parts for my 1966, changing from a manual drivers seat to a power seat, bought from Mort, perfect parts.
Mort is a member of the Southern Ontario T-Bird Club (so am I). He has published many articles regarding T-Bird restorations. Suggest you contact Mort regarding your power seat issues. Mort is not a business but a knowledgeable T-Bird collector and as a hobby restores some T-Bird parts. Power seat parts I purchased from him, parts he restored, were perfect.
