1970 duster with electric cut outs?

If your having trouble putting TTI'S on your doing something WRONG easiest set of headers I ever installed..you'll need to use the shorter filter,it fits no problem or you can use the longer filter using the adapter..
my bad! it was me! all I had to do is lift the engine another 1/8" to get header to slid thru on the drivers side! remove the filter and the passenger side will slid in with out lifting the engine. does the filter come out the top? I have no room below!
