(thanks Doug) – I own RDS that springs for Proflexes. I am waiting for a new batch to be made up so that’s why there are no little buy-it-now-icons on the website – they will be ready soon. We do a front and a rear spring – but if your nephews is really wee then a front spring will fit on the rear (it’s about 60% of the stiffness of the rear).

see link above, or contact me directly at: info At proflex dot. demon..dot<>..co.()..uk (without the punctuation), because, if you already have the speedpro collars then I’ll sell you a spring-only cheap.
