In moving the engine around, did you bend the oil pan? It dont take a lot to bend them up enough so the crank will not turn.
Also, the dakota and ram pans are different. Did you swap pans, but not the oil pick up. Again, they are different on the dakota vs ram and it may be jammed into the crank.

I think the oil pan is ok, I swapped the pickup tube with the V6 one when I put the new oil pan on, after that it didn't want to turn. You think maybe the pickup tube might be the problem?

Well looking on Rock Auto, it appears the 98 dakota 3.9 and 5.2 both use the same pickup assy. Did you use a oil pan for a 5.2 98 dakota or for a Ram? The Ram pan and pickup assy is different from the dakota. You need to match the pickup assy to the oil pan. And IMO it should be the ones (both pickup and pan) for a Dakota and not the Ram.

But all aside, if it was mine I would do the following, and most of this has already been suggested.
1. Use a 1/2 in ratchet and socket or breaker bar on the front of the crankshaft to try turning the engine, (both ways) and do this in each of the below steps.
2. Take the belt off to verify nothing is binding in the accessory drive.
3. Remove the spark plugs so there is no compression and this will let you see if it is hydro locked as well.
4. Remove the 2 bolts you installed in the flex plate. BTW, did you take the flexplate off of the 5.9 engine? If so, could it be on backwards and now is in a bind? I never had an automatic mopar apart. so I really dont know if its possible to put it on backwards or not, just something Im throwing out there to consider......
5. Remove the crankshaft sensor and make sure its not jammed into the flexplate.
6. Remove the starter.

If after all of this, and its still locked, (assuming, you never pulled any other parts off, such as intake, valve covers, distributor, etc. Then I would pull the motor, and then the oil pan.
This is just my opinion, but if the motor was running fine, you pulled it and now it seems to be locked, it is most likely something is jammed and can be fixed with no actual damage to the motor

I Used the 5.9 rt oil pan cause I figured it would be accurate, the 3.9 pickup tube, and put some new valave cover gaskets on it, the inside of the motor looked like it was just built that day. I have pictures, tried the breaker bar but it won't move either way. I might have to just pull it and see what's going on
