4 weeks sounds about right, but believe me it will be worth the wait. I bought a 4" extension for my lycoming, SAE-2 on crank end and SAE-1 on prop end. An absolute masterpiece. no visible toolmarks and heavy black anodizing, it also comes with stainless drive lugs and a thick crushplate. This is the same company that was woofter/saber in Fla. The owner (Judy Woofter I think) sold it to a fellow in Texas, after she moved to colorado, (I think her husband passed away). I think the long lead time has to do with machining several to take to the anodizers at one time, and it's also a one or two man operation. I will have to say it's probably the best looking part on the plane.
