Topper Horse Screw Pack

Hi Jonathan The bolts are M5 I have seen older Toppers with RWO fairleads instead of Allen but they have the same fixing centres.It may be more likely that an older boat has been fitted with something different in a 'make do and mend' way? https://www.tridentuk.com/gb/product-2-open-base-fairleads-7mm-al-a-182-2.html RegardsDavid
