Idler arm problem? Please help

otto37 said

Thank you for all of the reply. I believe it is the wrong Idler, probably the one the is correct for a small block but not the big block. Can anyone tell me the correct part number for an Idler arm that fits the Big Block? Thank you, Mike

The pitman is different for 383 cars.

All 67-72 A-body small block and slant six is Moog pn K7074. I do not have the old Moog number for the discontinued 383 Pitman arm.

The idler is the same for 383 and small block and /6. The 68-72 A-body ALL idler is Moog pn K7042. That's what should (probably is) on your car.
