Ballin - I have a full ERST 'box stripped back home, everything bar the LSD. If you want fifth gear alone let me know. I have a Stage 1 Bernie 'box in my Zetec Turbo Fiesta, and made damn sure it was full! Put the car on axle stands, filled it to the brim, left it half an hour and filled it again, probably took close on 500ml extra after that Had it jacked up to get as much in there as possible.
