hogie Posted February 27, 2009 Share Posted February 27, 2009 I just picked up a 72 240z and noticed some wonderful frame repairs after the fact. For the most part the rust is just on the surface and can be easily removed. However there are a couple of areas that I am very concerned about. These next two pics are the back edge of the floor pans as it rises up above the axle. I am betting these are important for structural strength, but I searched and didnt see any posts pertaining to repair/replacement of the rear frame rails. If i just chop out the rust and re-weld as opposed to rivet these back to the pan will it be safe or is a replacement piece available? Thanks Quote Link to comment Share on other sites More sharing options...
junglist Posted February 27, 2009 Share Posted February 27, 2009 The 240Z's never had rear frame rails. What most people do is get sub-frame connectors from Bad Dogz http://www.baddogparts.com/index.htm and weld those on over the original frame rails up front and add the subframe connector to the rear. If you don't want to purchase them, plenty of people have fabricated their own. Quote Link to comment Share on other sites More sharing options...
tonycharger72 Posted February 27, 2009 Share Posted February 27, 2009 For a reference a Hybridz member called Mull did an awesome replacement of his fraime rails and floor pans with very detailed documentation - can be viewed in the members section "project hugo" or even on youtube, lots of videos - same search title!
