What do you think (03 rust related)

[Jim Hunter]

Hello,

I was bought a 1974 03 for 100 EUR (!)
It is in good overall condition with very minor rust BUT it is badly rusted where the wiper motor is located.The hole is almost gone and it needs major rust repair here.Does any has fix this up ? What do you think? I also think to cut the bottom entirely and to weld the fresh air intake flush what do you think ?

Thanks!
