I have a 97 GMC 1500 short bed. I've done the ls1 swap into the truck. I've lowered the front and back, and installed a flip kit and air bags in the rear. I want to move the fuel tank behind the rear axle where the spare tire used to be. I'm trying to get better weight on my rear axle. Im getting high twelves in the 1/4mile at about 110mph, but my sixty foot run is trash. Im currently out of the country, but by looking at pictures online, the mid 90s Yukon looks to have a similar frame. I thnk that i might be able to intall a yukon tank into my truck. Im wondering if anyone has done a swap like this or not. Thanks for any information provided.
