Presumably your 20 chassis didn't need oil tubes running the length of the car because it didn't have an oil tank at the front?
Could be it was not dry sumped initially and might not even have had an oil cooler at the front (e.g. not combined with the water radiator).
IIRC the aluminium panels on the side of the footbox are pop rivetted to the vertical tubes & the body mounts (e.g. all but the water tubes which might leak!).
I vaguely remember other differences - there is some difference where the rear lower longeron joins the driver bulkhead and something like a water pipe exits in the same area on one version.
The lower rear (inboard) wishbone mountiing is wider on one than the other (e.g. one has shorter wishbones), and of course the upper rear damper mount is changed to accept the top link on a 22.
