I'm retiring my 99 Mustang Cobra (I'm original owner) and plan to use as many parts from it as possible for a 33 Hot Rod kit. Aside from the engine, transmission and some under-the-hood components, would it be possible for me to use the 99 Cobra IRS? It is not listed among the supported configurations on the kit order form. You may view a labeled drawing at http://www.drivingenthusiast.net/sec...s/99irs-02.jpg . I understand it's not as desirable as the 2015 version but I already own it and this would be a street cruiser with no hard cornering or drag-type starts anticipated. Excerpting a drivingenthusiast.net quote of Eric Zinkosky, Suspension Systems/Development Engineer-Mustang Vehicle Engineering from that era, "The independent rear suspension’s springs and Monroe shocks attach to the Cobra exactly where they did with the solid axle set-up. The only difference between the two systems is the addition of two bolt holes and "weld nuts" near the former Quad-Shock mounting holes. This four-bolt mounting system attaches the subframe mounting brackets to the underbody in a very secure way. And it’s such a match to the assembly tooling that the same machine that lifts the solid-axle suspension for V-6 and GT Mustangs also raises the IRS into place." (Entire article may be viewed at http://www.drivingenthusiast.net/sec.../specs/irs.htm .) My primary goal would be to save money, since I already own it. Thank you in advanced for any answers, opinions, suggestions, etc., anyone may like to share.
