Looking for replacemnent parts for my biltbest windows the operator is part number 233 D.C. and all I really need is the handle and worm drive which is broken. I am also looking for the closure latch for these same windows.

Time for a new operator. To get you started, take a look at the 39-027E and the 39-013 casement operators. You will need to order handles and also check out to see if you need to replace the track on your window. Respond back here with any questions you may have.
