Upgrade of Unitron Focusser.

Hi all, I would like to replace the existing focusser on my 4" Unitron with a 2" Crayford type to accept the larger eyepieces.Now, I might be missing something,but the existing focusser is held in to the OTA by a number of screws, but the screws have nuts on the inside.How do you hold the nuts on the inside in order to withdraw the screws. Cheers. Kevin.
