The beam tubes are fine, the endplates are guff but I assume you'd chop them off. I'm not sure how much a set of torsion leaves are worth, apart from seeing how much they've gone for on eBay.....
I'm down in Cornwall, just outside of Perranporth... as for money, maybe £25 plus any shipping (it'll all go towards kitting myself out for a charity walk I'm getting ready for)??? Pics on another thread - http://thelatebay.com/index.php?threads/bits-and-bobs-new-bits-added.79106/
