Yep, just like the lower picture! It is indeed steel, I thought it was
aluminum from a quick look.
I'd prefer a set of original outer rails, but something newer or something
I have to modify a little would be fine.
Thanks,

  I do have the inner rails/latch system for
tilting the box, they are
 plain aluminum. 
 Like the lower picture:
   
http://gunkies.org/wiki/BA11-K_mounting_box
 there? I'm guessing that's zinc-plated steel.
 Alas, I don't know who made those (may have been DEC themselves), or a
 source
 for them. _But_....
 I have some Chassis Trak outers which are almost compatible. (I say
 'outers',
 but actually many slide sets are 3-part; there's an outer which bolts to
 the
 rack, an inner which bolts to the mounting box. and then a third piece, a
 'middle' I guess we can call them. Sometimes the middle and outer can be
 separated, with a safety latch you have to release - but I think I recall
 seeing one set where you can't extract the middle mrom the outer - at least
 not out the front.)
 Anyway, the silver inners do fit into the track in the middles of those CT
 units - all except the two wheels at the inside end of the inners! Too bad,
 because I have no use for these outers, and would be happy to hand them
 over
 to you.
 The other possibilithy is that I _might_ have a spare set of the silver
 outers. I have 2 sets of the outers (2 left, 2 right), 4 of the special
 pivot
 bolts - but only one set of inners - at least that I can quickly find. Let
 me
 have a look around, and see if I'm really missing the inners - if so. I
 might
 be up for trading you a set of outers for something I can use.
