We are deep into a complete restoration of a 1955 180. We have decided to add a float kit- Yes, I know the work and expense involved, at least I'm realizing it now...... But this is the time to do it.

One part of the kit we don't have are the lifting eye bolts. Cessna wants upwards of $600 each and we have been unable to find good used ones thus far. 

Are there aftermarket parts available?
Are there different rings you all use in lue of the Cessna parts?
OR
Does anyone have the thread size, and shank length of the Cessna rings, we may be able to make our own or find something that will work.

Thanks,
