customizing a ram van

I have a client who wants me to find and customize a newer Dodge Ram Van for him (1995 or newer). Does anyone know anyplace where I can find custom parts for these vans, i.e. suspention, front air dams, carpet, headers, exhaust, performance engine parts, ext. If you could give me websites that carry this kind of stuff it would be very helpfull. Thanks

How about; www.jcw.com and www.summitracing.com or www.jegs.com and maybe www.groundforce.com
These are some companys I purchased a lot of parts from for my 74 chevy pickup restoration and customization along with ebay.
