Hi guys, thanks for all the tips and offers of help had one last go today with a sleeve anchor from selco, plenty of wd 40 and heat from the wifes hairdryer.
It is out!! Had to gently tap from the blind side but once it was moving all was good. Bit of corrosion on where it passes through the left lug. Any longer and i reckon it would have seized up totally.
Phew.... very pleased with myself, time for a beer ð
