classic motorcycle forum

I have a 1945 triumph 3hw, which was taxed for 6 months back in 1947.  I have had it for twenty years, and every time I think about putting it back on the road I hit the same problem, I have lost the clutch rod and and bush.  Non of the dealers I have e-mailed or in the past  sent snail mail, has offered a spare.  Can anybody tell me where I can get the missing items, what are usable alternatives (i.e. off which machine), or let me know what the overall length should be so I can try and make one, if all else fails.

thanks....Gareth
