To protect the vehicle leave the restrictor in position for the first 500 miles of road travel, or equivalent in industrial operation, after which remove and discard it" - Your Operation and Care Manual, Universal Jeep Model CJ-2A, First Edition, 1946. </div> <bR> <div> That is quite a rare piece he discovered, considering how it should have been removed years ago.  It makes you wonder if any of the previous owners ever noticed the lack of power over the past 50 odd years.  I have a fifth edition 1948 owner's manual which makes no mention of the restrictor plate so its use must have been discontinued somewhere in that time frame.</div> <bR> </td> </tr></table></body>
