[Walys60]

That's the ONE thing I didn't replace on my '60 1500 GMC.

I looked through the suppliers I've used and found the below parts. Some look like a swap from the ball to roller bearings. Not sure if it is just maybe a wrong photo or if they started doing that at some point. Anyway, I was hit/miss with parts that were 'supposed' to fit.
