Keith,

Yes the 84-85 13B pan will fit........The 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 the 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.........
