67 Idler Arm Question..

Was 67 a one year only idler?
Yes
Rare Parts wants over $200 so no thanks on that one
It is a stout part but for 200??? Not worth it IMHO, except that it will last you 50 years unless you're car is a daily driver.

Does anyone know a reliable vendor/part number for 67 Dart idler arm
I recently bought one of the $65.00 ones and it was dimentionally very close to the last one that was on my 67 dart, not OEM. The main things i noticed is the hole for the frame side cotter pin was so high that i had to put a thick washer under the castle nut to move it high enough to be able to capture the cotter pin.
I think i bought mine on ebay but this one from pst looks just like the one i bought
Idler Arm

Another option is to find a 68 and up (not sure what the upper date is) K frame it uses a better idler design and is otherwise dimentionally the same.
