I just discovered that both my pittman arm and idler arm on my 70 barracuda are well worn. Since I have to replace them anyway, I wondered about going to the fast ratio arms. I have power steering and a gen 2 hemi with TTI headers. What problems would I run into to use these components? Would changing to them affect the alignment job that I just had done? I can replace them with stock if it is going to turn into a problem. PST seems to be reasonably priced, are they a good choice? Thanks!
