I've just today retrieved my '73 Boler
frame from the 'sandblasting and paint' shop. Mine (Earlton built) was originally fastened to the fibreglass body with 14 'lag-type screws'. I have also welded four secure angle brackets, one near each 'corner' of the overall body-to-frame mounting areas, and will thus 'bolt' the body to the frame, using appropriate large weight
bearing washers. I will also replace most; but not all, of the mounting screws, for additional security.
Am I on the right track ? further advice would be graciously appreciated !
