Would anybody following the build be interested in this in a kit form? Ready to install with very detailed instructions. Maybe even 3d printed templates. All you would need are coilovers. You would get a choice of including a sway bar.
As far as the rear end housing this will obviously fit a strange 9”. The upper housing tabs will be extra long so they could be trimmed to fit a 8-3/4. This will not fit a mopar Dana. Although doing a little bit of research it maybe possible to fit a GM Dana that strange makes for A body GM cars. If yet to test fit that housing. The 8.8 is always an option too. This is resembling a foxbody a lot so that could be a good option also. Again the user would have to fab or modify mustang upper control arms to correct length.
