Obviously you will need an axle. I've never done a swap like this but I have researched it a bit.
First you will need a straight axle from a 94 or newer Ram. Unless you want to use a leav spring set up. In which case you will need to get an axle from a 78 - 79 Ford F-150 extended cab. They used a leaf spring set up and the differential is on the proper side. The single cab F-150 have cast in radius arm mount and coil buckets.
Also, you'll have to swap the rear axle as well or you will have two different wheel bolt patterns.
You're about to undertake a serious operation.
