Low/Moderate Income Households 2001-2004

I am being asked to try and locate low/moderate income households by census tract in Suffolk County for the ACS 2001-2005 period. The census data explorer doesn't go back that far, and the HUD User Exchange, which provides this information for the Community Development Block Grant, only posts data going back to around 2009. Does anyone have a suggestion how I can obtain at least the raw data, for which I can do the calculations for LMI? Thanks.
