Do the bolt holes in the spinner rear bulkhead (S-602-1) have to be drilled out to 3/4" to fit over the lugs on the prop extension? I am assuming so but wanted to make sure before i opened them up.

Thanks,

I had to drill mine to fit. But just be careful and make sure you are drilling to the correct diameter. Make sure its clamped down good when you drill it.
