Should have some pics and progress soon - had a frustrating day on Saturday of four hours effort for zero progress.
On the upside, I picked up this bargain of the century complete with the cross member and all the fittings that aren't shown in the pic.

I don't know if I will use them, but for £2.20 I couldn't resist.
