I'm in the process of removing the 351c from my 73, since I have never done this before, I'm following the Engine Removal and Installation process from a 64-73 Mustang/cougar Chilton's repair manual. Everything has been going fine untill step 12. Remove the flyeheel or converter housing upper retaining bolts through the access holes in the floor pan.?? Can anyone explain to me what they are talking about. I assume that if there are access holes in the floor pans they are under the carpet, however I can not find them. Am I way off base here?
