I dont know what i am doing but after asking questions on here and some google i went with a Gast rotary vain 0523 (supposedly easier to rebuild if needed in the future) with the vertex double diffuser. I opted to buy everything individually rather than a package to save a couple bucks. What I saved in money I may be spending in time!!!! I should have it in a week or so but that is what my research took me.
