Almost ready with new/updated diff covers for 503.
New model is longer than short ones for 511, just to make sure no small stones enter the lower hole on the diff cover.
Still held in place by upper bulkhead. So no additional screws or actually less than with original parts.
Still there is room in front of the cover if you want to add center weights.
More info to come, have worked on some other parts for 503 as well.
