hi, jock
sorry but i only just spotted this
but the hard wood sounds the simplest method i,v done it 100,s of time,s on big trucks nomally after pushingor pulling them nearly straight against a wall or steel stanshion then removing them and using a hardwood block and another bigger block to thump/knock against and of course a big hammer
but youre,s does,nt look to bad so maybe it will come out easy
good luck
mike..
