Depends on what you call late model and little modifications--------
You can build a package using the front crossmember and a -arms/steering/suspension to adapt to what ever frame structure you choose as well as the rear --however in 1997 they went to a rear trans/differantial/suspension that was quite advanced and it will get complicated. I got a complete rear package along with the torque tube for a build for a friend with a 34 truck. also sourced a cut out of the chassis structure so I would have all the diminsions/geometry of the vett to mount under the truck------

If your frame is bad/rusted/etc I would suggest sourcing a replacement frame from one of the builders to use the vett stuff on------
not putting your stuff on a vett frame
