Hey Myles,
If you are referring to the padded dash top, pretty simple. Attaches with two screws that hold the turn button on about middle of each far edge of the padded top and one screw with trim ring towards the corner by the windshield. I am attempting to attach a picture from the Anderson/Moment restoration book that shows this. Plus the rear view mirror screws through the padded dash top to the scuttle sheet metal underneath. If I cannot attach, send me your e-mail and I will forward to you.
Regards,
Mike
