Doug's D450 gaskets

Misunderstood you. The gasket that I spoke of are the ones for the single tubes that bolt together. On my old set of 450's I have the 2 center tubes on the driver side that bolt together. On the passenger side I just have 2 that slip together. Not sure what the newer 450's look like.
Yes they have two slips and 2 that bolt together, so they are the same.
