Hi guys.
Thanks for your tips. I had on bullets which weren't straight through, they had some sort of baffle in them. You couldn't see through them ,looked like they had a side step inside them. They weren't bad but didn't give me the rumble I am looking for. Will look into packs that are straight through design next unless anyone else has any other suggestions.
As for the AMC 360.. the body is sitting on a stretched grand wagoneer chassis with the front axle narrowed to fit correctly under the fenders. It rides like a caddy not a truck which is great for the long hauls. This is just a toy to play with, street only.
Thanks again
Willys
