[R-390] Interchangeability of RF Deck Mechanicals

Fri, 13 Feb 2004 11:40:27 -0800 (PST)

The parts "should" all line up exactly as they were made from the same drawings
and gauges.

You should not have any problems getting it to fit up.

The only noticeable differences I know of are the late EAC RF and IF mainframes
which are made differently from the other makes.  EAC got permission to do this
and it is reflected in their drawings.

I know of no differences in the slug guide plates.
