1994 Ford F-150 replace rear freeze plug

The way I did it was pulled the carpet back under dash and cut a hole in floor using a die grinder the hole was mabey 4x4 then I repaired hole with some good old fashioned Duct tape replaced the carpet and filled her up. No is the wiser, the other method is to pull the exhaust loosen the tranny and let it puul the motor down, then you have access, my way took 35min
