I think I'm gonna cough up for one.
??? What do you think is missing in the Jed's Machining kit. His comes fully assembled (welded & machined flat), is steel, and offers either 4340 shaft or resplined. It also had the gaskets, bolts & breather fitting. I got the resplined shaft, because it was all he had in stock and I was in a hurry (I'll probably upgrade later). Cost was $540 + 30 shipping. Neither Jeds or ORD had one in stock when I called. Jeds was cheaper and was able to get it out same day.Jed's is cheaper but that's because it's not an all inclusive kit, ORD & NWF kits are.
For me, I went with the ORD kit. I like the one piece adapter.

If you're a star member over on pirate, NWF is having a giveaway. I like my NWF doubler, and they warranty their product...but I don't think there's much of a strength advantage between the ORD one. ORD is cool tho...because there are less moving parts...the NWF just gives the advantage of clocking capabilities.

600 bucks for a doubler seems cheaper than re gearing my axles
You gotta add the cost of front and rear driveshaft modifications for a doubler. That will put you over the $1k mark.
