I just got a quick ratio box from this guy, I had a core and I picked it up so no shipping, cost me $120. He rebuilds them and converts them to quick ratio, direct bolt in, factory hoses work, no messing with hose adaptors. Cost is more if you don't have a quick ratio box for a core. If you are on Facebook check him out, really nice guy to work with https://www.facebook.com/carhex1/
