As advertised. Were the correct lines for a 1970 Skylark with a 350.

Quality and fit is great.


These trans cooler lines seem to very closely follow all the curves and bends of the originals. We shall see when I try to install them soon. It was time to replace the originals on my 52 year old Buick "Ruby"
