Anyone out there have any suggestions on where to look for the offset upper A arm shafts?

Any auto parts store that carries Moog should be able to order them. I found a part number listed on Federal Mogul web site K5250 for a 68-72 chevelle 2 per pkg., they sell for $38.79 on RockAuto's web site.

Last I checked, the offset cross shafts were $40 each.

IF you are looking for offset cross-shafts because of a tall-spindle brake conversion, and you can't get enough shims installed to align, there is another option. Two pair of longer Grade 8 bolts was about $5, but you have to be clever to figure out a way to keep them from turning in the frame bracket. The originals are knurled under the head.

I talked to ARP about building these bolts in a 1/2-3/4 inch longer configuration, but they didn't have much interest.

No, it's an original disc set up.

Just a bit of frame sag, and I want to compensate.
Easier to shim the difference than live with camber wear.

thanks

Moog K5250's are pretty nice pieces. They have a threaded end section for a large lock nut rather than the original threaded shaft with the bolt arragement. I've seen bolts actually walk right out of the shaft, so I think the nut will be a lot better. They come with original style upper bushings, washers, and nuts. Cost me $38 and change each at my local speed shop.

I've seen a lot of "frame sag" that turned out to be rotted bushings. New bushings put the control arms in the right place, and the vehicle was alignable again.
