There are links to most of those places and more here: Parts Sources.

You can buy just about anything. Also don't forget that for other parts, many Aussie companys will ship to USA.

I would also like to recommend Classic Datsun Motorsports, in Vista Ca. Also Design Products Racing , in Huntington Beach, Ca. They do alot of suspension components for race and street, If I'm not mistaken, datracer on this forum, as well as myself, use thier stuff. Top quality stuff. Don't forget your local Nissan dealer can still get some things...

There may be some performance upgrade parts that you just won't find here. If you can't try "feral" Errol at datrats.com.au. I've bought from feral and it was a very smooth transaction. I was very happy in the end. He even packaged up some parts I'd bought from another member here and sent it with the parts I bought from him.

For more run of the mill parts, I've tried rockauto.com, local parts dealers and local nissan dealers (or try courtesyparts.com - the nissan dealership located here in dallas known for the ability to get hard to find stuff).

With more specifics we can help a little more. What year/model do you have?

Classic Datsun Motorsports is in Vista ,Ca. just north of San Diego. Les Cannaday is the owner and he has or can get any part for your car. Hell he even races a bad ass 1200 coupe, his phone # is (760)940-6365.

I've had good luck with

www.rockauto.com
www.napaonline.com
www.partsamerica.com

I've replaced brakes, shocks, ball joints and quite a few other things, and got them mostly online at the above places.

give us a part and we'll give you the place(s) to get it

there are a few places, bill's datsun shoppe, paul's fab on ebay, ground control, and others.

for replacement parts, i use partsamerica.com and never have a problem getting parts.

most parts are bolt on, once you find them.

I've read and re-read the tech section and i'm still left with a gazillion questions with regards to doing conversions for my car. I would just like to upgrade my brakes and suspension (shocks, springs, Poly bushings, swaybars, etc) and this is a pain in the butt hunting down the parts... in some cases I need to make them...??? which is hard if you dont have access to some of the tools (Welder, etc..)

Are there anywhere in the USA or online I can just buy pre-fitted parts for my car not having to custom make them myself? I just dont have the time at this point to spend hunting down all the parts to make a hybrid part for my ride.

Any help or pointing me to the right direction is appreciated.

Thanks!
