It depends on how much lift you want. For 2-3" of lift I believe you are pretty much limited to strut spacers. This is certainly the most popular lift option for them. There are a lot of options for strut spacers and you can pick them up anywhere, you're issue may be a company that will ship to you. I can't recommend a brand for spacers, I've never used any. I would go with metal spacers though if I was going to install some, just a personal preference. In your situation I would identify the brand you want and look at Amazon, Alibaba or something like that.
If you want more than 3" you'll need to look for a used or new old stock 6-8" from Rize Industries.
