you could upgrade the 68~72 or 73~76 arm to a roller bearing and be cheaper than just the 67 arm. sheesh!

hell, you could probably grab a new idler and K for the price of that arm!

i've personally torn the mount on four different 64~66 cars (same design) with "only" 205's fitted-- granted, performance/track tires). and had a client start to pull one on his 67 dart with a 383.

understandably, on my early A's that was absolutely above and beyond any kind of normal conditions of use, but on that 67 383 car the dude is a old man cruiser rolling on 14's still.

i converted the early K to double shear and ran the later arm, on the 67 i wound up swapping the K to 73~76 when he opted to go BBP brakes.
