Series 3 short u-bolts

Does anyone know the right part number to search for. I'm after some short U-bolts for my rear axle. It has gb-springs parabolics and I'm trying it with two leaves (helper removed). I found one pair that will work in my random pile of bits that have a longer thread but they will need about 1" sawing off each one. The only other "short" ones I found are rotted to buggery.

I've tried looking in the catalogues and various sites but there's little to tell which are the shorter ones (or ones with longer threaded portions).

Cheers

it looks like they are sold in 'leaf measurements' if you know what i mean, eg. 'suits 9 leaf' or else to suit lwb/swb and/petrol/diesel....
so if you find what its compared to it might work..... is yours swb or lwb?? - have a look down the page in the link and check out what it might be compared to - http://www.rovahfarm.com/seriesaxlesandsteeeringpage3.htm
just a couple of suggestions......
