Thanks for all the info , here is the thing ... I have a set of spec 2's (now as pictured) , they were intended for a 1977 rd400 which I am in the midst of finishing , last weekend I bought a 1981 rd350lc , I still have to pick it up this weekend , I was wondering if those pipes will bolt up without too much effort to the Rd350lc , thoughts ?
