Really weird ,googled the RH 3958562 #, most hits came up on a site called Fast Lane,mentioned this # a lot,says it is for a 73-74 350 ,named a bunch of car names I never heard of,they are GM cars but all of the posters on the site are in Austallia and New Zealand? Really wondering WTF I have .Also mentions the LH part # that partially matches the partial # that I can get off of the LH exh. Manifold. Looks like this is a question for the site gurus?
