Well hello!

I'm back again after a year or two.
Have some reading to catch up.
Back then I had a Fuego gearbox in my restored Banks Europa 62s, now I have 306 rear suspension in the trailer for my restored 1964 historic open wheeler.
(Bought a Clio for my daughter within the period.)
I need more help now, of course.

I want to uprate the 306 suspension.
I've read all I can find on torsion bar and stabiliser bar sizes.
I currently have the minimum 19mm diameter, so most anything from another model will be an improvement. I've placed a 'wanted' adv.
