I listed these on ebay myself. The item number is 2442236039 I am not sure if this is proper use of this forum or not but just thought I would stick in a shameless Plug! Hope it is OK! Any way the manifold might be Buick but I beleive it is Olds although the (3) Rochester 2 Jets on top would probably work on some other GM's out of the late 50's or 60's. Any way I am pleased they are gonna get a new Home!! Bid till it HURTS1 Ed
Ed: At one time someone posted a link to a site which had pics of all the different manf. 3x2 set ups. Anyone else recall that post?
