Default 403 rear quarterlight water drains

Just finished the offside inner rear wheelarch welding. Now to tackle the superleggera frame immediately under the offside quarterlight, which has clearly been leaking for years (hence the rotten inner wheelarch!). The frame has rotted underneath where the blocks of wood go. The rearmost of the two blocks of wood has a hole through it, in which is installed a metal tube, which originally had a rubber tube pushed onto it, which threaded down through a hole in the inner wheelarch. This looks like a poor design, particularly since the metal tube was simply pushed up against the underside of the hole in the aluminium body. In my case, water has leaked round the outside of the metal tube and down through the wood, rotting the wood and eventually the inner wheelarch. My thinking for the rebuild is that with modern sealants available to seal down the rubber quarterlight mouldings, that the best bet would be to seal up the hole in the aluminium body, get rid of the drain altogether, and make a new block of wood without the drain hole. Any water would then just stay outside! Does anyone have any thoughts on this?

Thanks

Mike
