I would like to buy the whole set up in 1 to add the needle valve and I'm wondering if anyone can help me out. Here is the replacement for the original http://www.appliancefactoryparts.com/search/part/1054017/146167 and this is the one I'm thinking of getting http://bayouclassicdepot.com/m5hpr_propane_regulator.htm but the ends look slightly different and I don't know if this will be a problem?
