Refitting the Re-fit

Realised the Funnel was the wrong type so changed appropriately, spent about half an hour trying to figure out what was wrong with the body; realised it wasn't long enough...or tall enough...or chonky enough...now looking at it the centre dome is in the wrong place, and the front one is different... beginning to think the original specs on that schematic I found were wrong, or maybe it was the original, and they changed a lot with multiple re-fits...much like myself.
