I purchased my rear IRS from them, no issues. Pretty straightforward process, just make sure you get all your questions answered before you place the order. The other thing to watch is if you don't have a shipping doc, or a business with a Hi-Lo to offload it. You will need liftgate service which is a small up charge.

I also got my engine from domestic performance recyclers. Got a really good deal on a low mileage gen 3. Videos of it running etc etc, https://www.domesticperformancerecyclers.com/
