Lowering a torsion bar, nick method...

[Sinbad]

So after a day of faffing about, sort of got here where I want her    not sure if she's a bit too low, but I guess a good drive will settle it. As she stands, 40mm between the tyre and the arch. 
The only thing that is worrying me is that a 2-3mm gap has appeared between the arm and the axle on the left side    Everything is buttoned up, and I've had the ARB tabs on and off a couple of times to make sure they're fully home, tried belting it to see if somethings stuck  - but still this bloody gap is there, showing a couple of mm of axle shaft 

Anyone got any ideas on that?

While I'm about it - 51€ for a pair of 20.5mm torsion bars - for a Berlingo, but can anyone confirm whether these will fit on a Cab? If they will, I'll bite their arm off 

Cheers

Answering my own question in case it's of use to anyone else in the future - Cab torsion bars are the same as every other 306 - 1063mm long, so the Berlingo's would be too short - although not by much since the splines in the arms are longer than the splines on the TBs - but I don't think 15mm of spline would cut it for very long...
