looking at changing oil over weekend got filter but was hoping to drop out the round plate on bottom of sump to remove the strainer, but when i had a feel round all i could feel was the drain plug

if i have this right the super has a pipe with a strainer fixed on the end and you have to remove the hole sump pan to get to it,
but the standard dexta has the round plate with the strainer fixed to it.
could some one have changed the pan and fitted a super sump pan, do they fit or did fordson change the the dexta pan to the super pan at some point ?
i dont fancy dropping the sump pan as i only have 2 hr spare to do oil change, from other posts it looks like front axle need to come off and engine may need supporting as the sump is structural to the engine and could crack the block if its not supported.
sorry for the long winded question, it looks like my old blue girl has had a few modifications made
many thanks
