Re: Volvo 280 Drive
A good prop shop can, to some extent, add some of the extras you may desire, but typically, with that type of drive system, high rake doesn't work well, but cup can be added to a 19 to make it a 20. Cup can be added to the tips to change the rake slightly.
That Drive system just does not exist in enough numbers nor applications to provide a large enough market to mold props for.
