I'm considering a build of a 1975 Olds Omega.  I want it to be a "g-machine", but it seems all the suspension offerings stop at 1974.  The purpose is to build something different, inexpensive (relatively), and fairly simple to build.  But, maybe this is the wrong car for that (if the parts packages are not out there).  I know X Bodies shares part with the F Bodies, but since the sites I've checked don't note any interchangeability, it makes me think the aftermarket may have passed the '75-'77 X Bodies cars by (as did PHR in it's list of 9 cars to consider building).  I'm a bit new to the hobby and would like thoughts from others who know what I'm getting into.
