Welcome to the site from California. Since you are at this point, what would you do different ? Are your inner fenders going back on ?
Greetings from California as well. I'm in the Northern Cal area.
When I started the project my hope was to be a plug and play operation. Bolt in, hook it up and I'm on my way. However, the turbo complicated things quite a bit. As well as the 4L80E. Hindsight I probably would have gone 4L60E (built stronger) and I could have saved the crossmember/driveshaft mods. Dirty Dingo makes a nice AC relocation bracket arrangement and I could have called it a day using the bracket adjustments. But I had already invested a boat load in the trans and custom converter. Oh well...
As much room as the 73-87 trucks have under the hood, there are still many limitations to certain swaps. The newer Chevy trucks have a pretty different front chassis clip and engine set back. My mistake was thinking, heck if a 454 fit, anything will fit... wrong..
I've since installed new inner fender liners. Just so much easier to work inside this thing with them out!
Sorry if my post is in the wrong section. New to the site wasn't sure where this should go. Just wanted to help any others that were contemplating this type of swap as I've read around without much luck on what works and what doesn't.
