I have an '88 ram 50 with 4 cylinder. It belonged to my late grandfather. I know very little about these trucks. There really are not many running around in my area. The truck has been setting for quite a while and I would like to give it new life. Has anybody swapped a 3.9 from a dakota? If so maybe you could give me a heads up on what to look for and what to expect if I decide to tackle it. Thanks in advance.
