I've done it. It's really an easy swap.
However... you are now standing at a crossroads. The Toyota steering swap is the begining of an investment that will shape the rest of your front suspension. If you plan on leaving the front suspension stock, and like it that way, then proceed. However, if you are planning on adding some kind of independent front suspenson i.e. Mustang II, volare, etc.., you may want to wait and save your pennies.
Just something to consider-- (something I realized after the fact) The money spent upgrading the stock front suspension (including just replacing stock parts) to handle close to that of and IFS, you will be spending considerably more money that it's worth, much more than the cost of a complete IFS kit, and still not have as good a ride as you would with IFS. But if keeping it stock is your game, or just just plaing like the I beam axle, then by all means do it. I just wanted to put that out there as if I would have considered the costs involved before I had done the Toyota steering swap, I would have been hanging an IFS kit under my truck instead. I plan on driving the wheels off of mine and want it to handle and ride very nicely. It's gonna cost me more $$$ to achieve that with the stock-style front suspension and still won't quite ride or handle as nice. But if you don't care about that stuff, or you're satisified with the way it is, by all means go get that Toyota kit and get it in there!
Not trying to sway ya, just wanted to give you some food for thought.
I'll have to call CPP and see if I can get on from them. I looked at my invoice and though I got it off of E-Bay it came from an outfit called Gearhead Enterprises out of Iowa. Will try and call them too.
