Xea,I'm planning on purchasing 5000375 , 5000840 and a new dampener kit.Which dampener kit would you recommend for this setup,assuming it will all work on an 82 Ironhead.I have the stock buckhorns with 9" straight risers,Total height is 14",pullback is 11.5" and width is 28".The new setup would be 14" height,7.5"pullback and 31" wide.I figured with less pullback,the width would just about make the new setup the same,so I won't have to buy new cables or wires.If you agree with this and give me a dampener kit number to go with the new setup,I'll go ahead and order everything when I hear back from you.Thanks.
