The clearance between the front driveshaft and TH400 in my FJ just wasn't cutting it, and hopefully my solution will help someone in the future.
I ran across a few posts here about the Advance Adapters kit, but I was pretty confused at how it's supposed to be constructed ( as were other posters...). I went down to my local drive shaft shop and turns out it didn't make a whole lot of sense to them either. My guy thought he could do better, and advance adapters allows you to order individual parts from the kit.
- modified xfer case output flange from advance adapters: part #716372 ( only $25!)
- Neapco flange yoke (mates to AA flange on xfer case): N2-2-899-1
- Spicer spline (slip assembly): 2-40-1291
- Spicer sleeve yoke ( slip assembly): 2-3-8001KX
- Spicer C & B ( u-joint ): 5-153x
- Spicer bolt ( to bolt to AA flange ): 5-73-414
- Spicer washer: 500357-10 ( to bolt to AA flange )
I'm not sure if I saved money ( $340.24 out the door ), but this assembly is STRONG as hell and replacement Spicer parts are easily found. This shaft still requires a little modification to the side of the tranny pan, but instead of a hairs width of clearance, it's more like 1/2 - 3/4 of an inch. The u-joint, while a tad smaller, is a part # spicer lists for Toyota, so it's not using some small wimpy joint from another truck.
Hope this helps someone in the future.
