I don't want to say much on the auto swap bec I have not done it. I can say the physical swap shouldn't be hard, but getting it to all work IDK. The SRA swap is pretty straight forward. Is the 8.8 for a Cobra?? There are a few things you'll want to know. There are SRA swap threads that cover this. Search around and find it, it will be a big help. In short you'll need control arms for SRA, a Cobra pinion flange on your SRA, swap the Cobra IRS brakes onto your SRA, and SRA specific springs and shocks.
