Lloyd White has just published 4 new softcover spiral-bound books reprinting many Modification Work Orders and Technical Bulletins for various military vehicles. GPA owners might be interested in Lloyd's book titled "Selected Military Vehicle Publications of the U.S. Army and Air Force"
because it contains all twelve GPA MWOs from FSMWO G504-W1 to -W12 complete. These MWOs cover topics such as adding frame spring bracket bolts to provide better attachment, reinforcement of rear axle tunnel and walls, improved sealing of deck ventilation and motor cover, relocation of voltage regulator, addition of equipment not included in production, adding inspection holes to front floor, etc., etc. Should your GPA become land bound, this book also contains one TB on converting GPA front and rear axles for use on a GPW. Details can be found in the MANUALS subforum here:viewforum.php?f=91
Lloyd will have these books available for purchase at the Petaluma MV Rally in California this coming week of April 18th to 23rd, 2017, and later this summer at the MVPA International Convention in Cleveland, Ohio.
