   Keith,
      Yes the 84-85 13B pan will fit........T= he two larger bolt holes for the engine mount on the
center housing are not drilled on the 84-84 13B pan but the small 6 mm= bolt hole (Standard
pan bolts) is already drilled and threaded on your center housing (My = 88 housing is) and will
match up with the early pan so there is no need to drill the pan for t= he larger bolts........One
other suggestion would be to make a spacer (stack of wide area washers= ?) to fit in the space
between your existing pan and the CCI plate and go ahead and drill the= plate for a bolt and
sealing washer..........Should not be a major problem IMHO.........
