Hi there ..more pics for this group would be most Xlnt...
also are your 'shown' pieces the ones being sold??
you made note of that on the 2.0 'hot dog'..
the 1.7 and 2.0 are diff on the heat xchgrz cep't 75..
also looks as if the 'other muff' is a 74 if the pipe comes out of the side..
then that would be a 1.8.....(although useable for earlier)
it weighed a ton though..
the heat xchngrz for 75 were 1.8/2.0 combo...
most here like the separated shots..
looks as if yah have a bunch...
Cheers and good luck with your sales...
