Slant 6 6 into 1 JR/Mopar Performance Header

You are correct dartman those are '67-'76 a-body JR's yes they do hang a bit low
I bought early version in mid 80's square ports,half of which did not align w the ports
in the head.....6 hrs. of welding & grinding incl. adding nuts so the bridging washers had
something to clamp ! terrible. have 2 later versions w/ round ports much better& nuts
welded on 4u did unmentionable things to get one on my '64 GT man. box!!
