I am going to make some assumptions...so correct me if wrong:
1- I assume you are not new to recurves and know what your actual draw length is on that bow for a typical stance. Reason I ask is when I shot compound I was 31.5 inches...and thought it would transfer to recurve...it doesnt...I was a full inch shorter in the recurve due to shooting stance and draw style.
2- 3 Rivers only goes out to 31.25 inches on their shafts in 75-80. I would think if you truly need a 32 inch BOP arrow which is a 33 inch shaft to start on average...you will need to go custom. I would call Rose City, Hildebrand or one of the custom arrow builders here and see about custom lengths which will likely cost more.
Good luck....
