Photos of Stacks.....

Is there anyone out there who owned or knows someone who owned a pick-up with dual stacks from between
’70 – ‘99? We are building an advertisement showing the roots of our SMOKERS™ dual stacks. We know about Dodge’s 1979 “Little Red Express” but what we are particularly interested in are dual stacks inside the bed. If you know of a vehicle we will trade an MBRPinc T-shirt and hat for a picture that we can use. Thanks!
