full suspension rebuild

Good questions guys..

My mind set is that if I buy all one one company, I will get better service..and it seems that PST has it all. I asked them about shipping...free to all lower 48..but if you actually look at the shipping costs...my house is under the longest shipping they have and no discounts are forthcoming..sorry, that is just a buggaboo that I have,

I started pricing up the individual pieces using the PST poly set..I read a lot of negative stuff about poly..the main one being squeaking.. for racing, I don't think this would be an issue...but after playing with the site, I found that PST does the original as well..the link..

The leaf spring pads link is here..

The company says that fit a '76 aspen..I thought the aspen was a '77 but the '76 duster is the same as the '7 so I am a bit confused.

Is there another company that I can do one stop buying..does Hellwig sell all of the above ? I haven't found a Canadian company that can do this.

I appreciate the input..I only want to do this once :)

Thanks
