1992 Hiace, super custom Ltd. 2.4 LTE D. Block drain plug

Hello,

Has anybody actually managed to get access to the block drain plug and remove it with the engine in situ? I can just see it under the diesel pump, but haven't found a way to get a socket on it. I don't know if it can be reached by removing the cover in the front nearside wheel arch. I didn't have enough time to investigate that.
