The more recent Cessnas use a Nylon/Teflon type moulding that is a push fit over the front of the constant speed unit and has an angled flange where it meets the spinner. The distance is adjusted using shims between the moulding and the unit such that there is a firm press fit at the flange needed to make the bolt holes align on the back plate. There are no bolts on the front bulkhead as such. Balance and central alignment are critical. Using a torch inside a composite spinner can help in getting the bulkhead correctly positioned because the composite is opaque.
