A friend of mine dropped his field-find '52 "Binder" onto a late 1990's LWB Dakota. He said the length of the frame is much easier to modify than the WIDTH, and the the width of the Dakota chassis fit perfectly once he shortened the frame. He even kept the Dakota floor, firewall, dash, ECU, gas tank, etc.

It was a 6-lug truck, so he ordered black steel wheels (cheap) and used some old wheel covers he had lying around.

Most important: pay attention to the track width comparisons between your truck and whichever Dakota you use.
