it actually isn't that hard. I looked at pictures and had a go. It is relatively easy to replace the canvas and the seals. You will need a specialist tool to put the seal back in. I bought it from just kampers as I remember. Bought stainless steel nuts and bolts and a good strong needle to puncture canvas. Took a deep breath and went for it. I'm no mechanic or handyman but with money being tight I need to do as much as poss myself. I also enjoyed the challenge. Trying to find the thread on here about doing the job.
