Dell D630 Windows 7 64-bit Drivers

Hello Mr. Yip- Todd Naber here,

 I have a Latitude D630 (dual booting 64-bit XP & 64-bit Windows 7) with 8gb of ram and I'm finding it difficult to find Dell Drivers. Originally the Dell D630 had a 320gb hard drive with a Windows XP COA on the bottom of the laptop- but I purchased the D630 from Dell with a Windows 7 Upgrade years ago.
 The D630 hard drive died and was unrecoverable..,so I recently installed a 1tb Crucial 2.5" ssd and reinstalled Windows XP 64-bit and Windows  7 64-bit from both Dell CD's that came with the D630!

 The Drivers for Windows 7 64-bit are missing, so I was wondering if there are still drivers available- or do I need to use Windows Vista 64-bit drivers for Windows 7?
