Chris. Several are available from Abe Books from £29 upwards. Do a search for "M.G. Workshop Manual" by W E Blower. You can also get a new copy with softback, elsewhere on Amazon for £112.00 !
I tried to scan and send you just the page on C and J4 springs but I'm afraid that I failed miserably.
Thanks Colin & Rich, I have a contact whom I will be contacting today who has a copy for sale which I can collect at Stoneleigh, so I think I am pretty well sorted. I try to form a reference library, but always appreciate efforts ( like Colin & Rich ) to help. Much appreciated.
