do 68-70 340 hp exhaust manifold fit 64 barracuda ?

I guess everyone's experience is slightly different as far as manufacturing variance. My first '65 was a 2 dr. sedan w/ a 170 and 3 on the tree, manual steering and brakes. My Dad installed a '68 'cuda 340 and used the complete 'cuda exhaust system from front to rear, including the chrome tips after notching the rear valance. I helped with the install and don't remember him having to do anything with the column. I do remember it was close but nothing hit. My 2 cents for what it's worth. :)
