When I replaced a pneumatic lift ram on my SCM I contacted a company in Derby - SGS - tel no. 01332 576850. I ordered a ram at 4pm on a Friday and was told I could collect at 8 am the next morning. I thought that was fantastic service and the cost was less than 50% of the SCM part, I simply had to tell them the required cylinder dimensions, stroke, force rating and end connection details. I don't know if this helps, but it is probably worth a try. G.
