Would anyone know when certain chassis stopped using the almost universal 3/4ton style IFS(not torsion)? I hear my '62 could use anything '63 on up to '87. I know the normal cutoff for 3/4ton is '87 but I hear suburban front x-members are usable until '91. I have access to a 1989 g20 3500 series cargo van (8 lug wheels all around), any chance this is the same as the suburban due to the fact is "heavy duty"???
Also, does anyone have a picture of a stripped x-member that they've installed onto their '60 or older truck? Anything from a later ('89-'91) model suburban would be awesome!
Thanks!
