Need 46RH valve body

Just looking for a lead. Converting my non-lockup 46RH to lockup while rebuilding. Already have the other needed parts but can't find a VB that also has the boost valve (got one without it). Anybody know where I can order a 46RH lockup VB small port with a boost valve and tube? Only one on ebay and it's in Canada (tariff$$$$). A decent core or used VB is fine I'll go through it anyway. No more rebuilding shops with used parts in this area it seems. Posted a wanted ad here too.
