Welcome , looks like a good base/platform to start from .I have to ask why buy fender flares to lower the truck ? If you're going to put a v8 I personally would want to lift the truck .I'm guessing being an 89 it has a 2.0 ? That motor will last another 6 years if it's taken care of properly. I had almost 300k on my motor that was still running.before I just decided to rebuild it .
