[3 79cougars 1 77 t-bird]

I hate to see the cars go this way but I found a 77 thunderbird that has been through one derby that is for sale. it has a 400 engine. anyone know anyhting about strengthening these? it is missing the radiator support. I am hoping to buy this and finish it off so I can transplant the 400 into the cougar of mine. let me know
