My cracked spinner was attached to the back plate with 8 self tapping screws from the local hardware store. The replacement from Univair came with the proper screws (should I back them with some Tinnerman nuts?) but with 4 extra holes midway down the spinner. Since my old spinner had none such I contacted Univair and they said the 4 holes were to attach to a forward bulkhead which was introduced to stop the frequent spinner cracking. Would someone wise me up on this forward bulkhead especially on how it is attached to the spinner? I understand that its role is to stiffen the spinner. Thank you.
