Toyota Torsion Bar

Does anyone know or could measure a late 80's to mid 90's IFS truck or 4runner torsion bar length? I am looking at replacing the stock Land Cruiser anti sway bar because it will be getting bent on a regular basis.

I looked at Antirock sway bar kits and they are pricey and Currie could not offer much at all on how it would perform so I loose interest. I thought if I could get lucky I might build my own torsion anti sway bar.

You will need the front and rear mounts for the bar also, wont you?  They are splined, IIRC, so it would be difficult to make something without having those mounts to start with.  A really cool design would be to use two bars, each cut to half the necessary length, with a flange welded onto each one at the middle (or perhaps off-center depending on clearances).  Then bolt the two flanges together when you are on the street, and when you get to the trail, unbolt the flanges and rock on with full flex.

Not to be Debbie Downer, but welding on torsion bars does not sound like a good idea to me.  Best case you will affect the spring rate of the torsion bar (a torsion bar is just a spring); worst case they break where the welds affect the temper of the bar.
