The oil pan also needs to be the dimpled version for the A-body pitman/idler. Not all small block oil pans are clearanced. I can't be specific but from memory that was especially true of some of the aftermarket stampings. It's also a factor that the 273/318/340 pans are different than the 360 due to the larger main bearing diameter that changes the end dimensions. The V8 center link has been reproduced in the recent past. Still available? I remember it was pretty expensive. I collected originals over the years and still see them occasionally. Grab them while you can.
