Hi all, can anybody help me please? i've been looking for ages in all the usual places. do any of you know a site in the u.k that i could purchase these from please. thank you cheryl.

I would ask at your local horse /saddlery retailers or farm supply shop.

What breed is it for ?

You could build your own.  We did!

I'll pm you, because I'm not sure if I can put the link in.  The instructions are not on my site.
