help! i am missing hoses and vacuum lines on my 75 280. i have a chiltons and a benz service manual. they are useless for what i need. how do i find out where all the lines and hoses go? is there a simple diagram for this car? the carb scematic does not say where to hook up vac. lines? i would like to hook up all lines before making any decisions on this car..most frustrating car i have yet owned! very poor info available so far. is 1975 a weird car? thanks
