I need to replace the following parts on a 57 Chevy convertible. The body of this vehicle was stripped down, media blasted and, a major portion of the floor and inner rear quarter panels replaced. The following parts will be replaced but I need to know EXACTLY WHERE they go. - - - Both Right and left Windlace END BRACKETS for 57 convertible - - -The two Convertible Backrest Suppot Brackets ( fastens to the rear inner wheel wells to hold the backrest panel in place.) I would appreciate ANYONE who can provide me some good photos, drawing, tech sheet, diagram PREFERABLY with some measurements [email protected]
