WHEREVER YOU ARE GETTING YOUR INFORMATION IS INCORRECT. ANY 98+ BODYLIFT WILL FIT ANY 98+ TRUCK REGARDLESS OF CAB, BED, ENGINE, TRANS, DRIVETRAIN CONFIGURATION.
See how annoying that is? Caps aren't needed and results in being hard on the eyes to read.
Best bet is getting the 01-05 Performance Accessories Bodylift. They run about $190-250 depending on where you order. You can fit 31's very comfortably.
The bodylift shifter extention is the only part dedicated to a manual trans in regards to the bodylift. Everything else is the exact same. That trans extention does not come with the kit and must be purchased seperately.
