my friend made his own crossover steering arm by taking two(i foget which side they need to be) and doing some welding and grinding. He also made his own drag link. high steer is like 700 +/- a few bucks... He did it real cheap but with lots of work. as for SAS you can fabricate most of that stuff also like the front crossmember if your handy with a torch and a welder. I would personslly go ith the sas. youll be so much happier, and so will your runner. Another issue is finding a frt axle. you can ussually buy them for around $250+/-........
