Do the 66 and 67 B-bodies have stud mounted idlers. From the 444 source oil pan list it seem the the big block 66-67 B-bodies take the same 383 pan as 383 68-71 B-bodies.

The Milodon pan might not have the same fit for a 66/67 idler. I'm even surprised they offer a Big Block road race pan at all. It's really tough to fit road race pan in Mopars because of the surrounding K-member and rear steering linkage. Did others say it just didn't fit 66/67 B-bodies or are they having that problem with all body types.

In my opinion you should run the 70-72 B-body K-member if you are interested in handling. The 66/67 stud mounted idler flexes. The unique 66-67 idler will or allready has been discontinued. The wide 66-69 style sway bar limits the backspace rims you run in the front and they hang down a little low and bushing straps got beat up.

If you are will to pay 300 for some custom centerlink with a good chance of someone botching up the geometry. Why not spend $75 to have some notch and weld you Milodon pan.
