I'd be talking to MacDonald Bros about that. 20mm of shims is shitloads.
Sounds like what they have sent you is the problem.

I don't have an LJ manual, but the LH one says to not exceed half an inch (12.7mm) with the shim stack.
I just noticed that you joined in 2005 Heath. You must have been about ten years old!!!

I was 15... which means I've been on this forum for more than half of my life, haha.

They recommended spacing it out, can take some of the gap with a machined thick wall tube.
In some cases, can modify the arm a little, shorten the length up.
I know they know about that problem with lh/lx, these are made on a common platform, used not just for torana’s, other early holdens too.

Good stuff.
Sounds like someone should cut your upper arms apart and turn them into a nice shorter pair with the balljoint offset a little.
I guess you have to send them back? Haha.
