Sunroof

[botoxdr]

I am restoring a 10 seat O319D in Sth Africa and also a regular 319 Bus. Does anyone know where I can parts or a whole new roof. Webasto no longer stock parts. Also looking for glass including roof glass/rubbers and many other spare parts.
I am considering a conversion to 2.5 litre diesel Sprinter motor and automatic gearbox. Any suggestions?
Has anyone tried a Mercedes 5 cylinder or V6 or V8? Peter (Sydney, Australia)
