i just traded a 2000 sentra for my 2000 blazer. So far I have replaced the Head unit, rear door speakers, left front hub, all ball joints, that trans pan, the trans cooler lines, transfer case seals, front axles, and had front diff. rebuilt.
Cragar soft 8's
Sony CDX-gt520 CD player with iPod adapter, Cerwin Vega stealth series 6" components in the back doors, the front speakers are aftermarket but I don't know what they are, they were there when I got it.
