Here are two pictures of Power Wagons of the IDF. Although open cabbed, they are not fitted with the M601 windscreen but with what looks like Dodge WC52 windscreens.
Most likely, these were supplied as chassis/cowls, with windscreens and rear bodies being fitted/manufactured locally.
Notice the similarity with the Dutch KNIL Power Wagon?
Both armies clearly had a need for a replacement of the WC52 Weapon Carrier, and the Power Wagon with a rear body made to suit was clearly up to the job.
