Thanks for the edit.

Sorry, but I'm not so sure. The front track on the 46 truck is 55.8 in (1.42 m) from wikipiedia, (would they lie to me?)

Here is a lot more info, most of it misleading, they also say that the Dakota will work.

As Gene says "The track width of the 1st gen (88-96) Dakota is about 60". I have just done a Dakota front frame transplant (build pictures on this site) on a '56 car with a measured wheel mounting surface (WMS) to WMS (not the exact same as track but close) of a 58 1/2", The Dakota WMS to WMS is a measured 62" and even with very negative off set wheels (Mustang) it is almost to wide.
