I thought this might help some owners of NAF cobra's. I've had mine for 2 years with no documentation of its' history or components other than it was assembled by NAF in Arizona in 1988. What I have discovered so far:
302 Hi Output V8 from a 1985 Mustang GT
Borg Warner World Class T-5 manual transmission from 1985 Mustang GT
Differential is Ford 8 inch from a 1971 Mustang
Front disc brakes are from a 1974 Mustang II (replacements for the Mustang II will fit)
Hope this helps.
