My Square Jaeger Speedo is in need of reconditioning and I need to take it out. I am anxious to retrieve it properly. Can it be extracted from the back or will I need to bring the dash forward? Could anyone describe a blow by blow or have an exploded diagram please. From lying upside down with a torch it seems to be in a steel cradle, does this come out in one piece with all dials?.Wood dash first? If anyone can assist before I start would be helpful. Thanks.
