you say if it is in gear that it does not roll freely, if you are trying to move it when in gear, pop the hood and you should see the engine belt turning.
if in gear and tires are rolling, the engine will turn with a manual transmission

With, say drivers or passengers side in the air and rear tire off of the ground, since we have open differentials you can try to turn the rear tire, even in 6th gear you should bot be able to turn the tire, take out of gear, make sure the wheels on the opposite side are blocked so no chance of forward or rearward movement, take out of gear and see if spins freely or of there is any difference.
