I put a lot of Jones turbine SS mufflers on diesels. Never had an issue with them. It does sound great Bam. Funny you post the lights pic. I was going to ask which housings you used. The ones I put in my 72, one has no cracks etc but is gaining moisture and I could raise a gold fish in it.

Your truck would look sweet with a shaved and smoothed intake. You'd still have to address covers for the coils but I like the looks of those better than the oem panels.

Am I seeing this right? That you're working out side on it? If so I'm jealous. Haha
