9" with the ends cut off HQ trailing arms and used as upper control arm mounts.

For an extra $100 I would go adjustable just because I like adjustable things.

McDonald Bros usually use SuperPro bushes. If you want to use SuperPro then check the duro that McDonald Bros fit. You may want to go a softer duro (check the SuperPro recommendations on their website ) or have rubber fitted instead. McDonald Bros will supply without bushes.

The wheel moves backwards with lowering, so you need to pull it forward if that's the case.
And the angle of the diff changes so having adjustments top and bottom can allow you to push the snout of the diff up.......

Also they asked if i had torana or hq mounts on the diff as they now make the upper arms to suit what mounts you have should be a straight bolt in job

Something like this.
SCA Air Hammer Kit
Otherwise make your own puller. See this thread.

9" with Torana upper control arm mounts with McDonald Bros arms binding before the bump stops.

Without looking at a unmodified diff it looks to me like someone has mounted the the bracket on the diff back to front, if it were the other way around it would not foul and has the cut out for clearance
