I'm planning on doing a front end transplant using one of these, seeing the Arntz was originally made with an MG front suspension. They're made 51" wide for MG V8 conversions, and 53" for Arntz/Butler upgrades.

I currently have a front sway bar but this new front end doesn't come with one.
Just interested -- who's car has a front sway bar? Is it adjustable? Have you tried going without it?
And for those with Jaguar rear ends, do you run a rear sway bar?
