sorry for the delay in reply, I've been away. The front springs are from Robin Hood so not sure on poundage, I had a bit of trouble sourcing the damper insert as all the pattern strus I ordered seemed to be welded together and priced abit high, in the end I rang GBSc and they had some knocking around.
If you don't have them alredy you will need some bearing rings for the top also, if you do a search on here for 'exmo' you should find a link for the correct bearings aswell.
