Hello, I have a Mack B-model i am currently starting to restore. I am looking for a website that i can order a dual stack kit for this truck. It has a stock single exhuast on it and i am looking to put dual chrome stacks on it. I have found many sites where i can buy the actual stacks but not any that i can but the kits to adapt the dual stacks. any info would help.
