Okay here's what I have:
50 Series Flowmaster - 3" in/dual 2.5" out. Excellent shape, clamped in place. Has heatshield. Used for about 5K mi or so. $50 shipped OBO.
16" Electric fan - off a '96 Mustang GT. About 50K mi or so. Comes with factory plug and about 12" of harness. Can be wired up as a high or low speed fan. This thing will move some serious air seeing as how it can keep a Mustang cool. $80 OBO.
Autometer Fuel Pressure Gauge - This is a 1.5" 0-100psi gauge. Easily will screw into fuel rail. $35 new from Summit, $20 shipped.
Hayden A/C Thermo Relay - 30A replay, Fully adjustable from 150-220* or so, Thermo probe, wired up for LS1 fans. Simple to install, all you need is a constant, switched, and ground. I can walk you through the install. $45 new from Pep Boyz, $30 shipped.
I have plenty of references if needed. Lemme know via reply here, PM, or e-mail.
