I guess it all depends on what you want as a final product. You could go with a straight axle kit from Speedway Motors and have the gasser look to it. Lots of eyeball, but a little iffy in the turns at speed. You could graft a MII crossmember in and buy some of the nice tubular upper and lower arms if you wanted good handling, r&p steering and 11" brakes for the street. One of the members on here said at on time he grafted a Fiero front end onto a street rod, so you may want to look at one of those before you decide what to do. Grab a copy of Street Rodder from the newstand and look through the suppliers.
