•
PlywoodFloor Top: If wood is used in your vehicle floor, special attention shouldbegiven to the
quality and integrity of thewoodmaterials chosen. Some factors to consider are thermal
conductivity, water vapor andgas permeability, acoustical andelectrical properties, andmoisture
resistance. Ford recommends aminimumof 3/8 inch thickAPA (A-C, B-C, or C-CPlugged)
quality underlayment exterior gradeplywoodas a topof floormaterial, basedon research
completedby theAmericanPlywoodAssociation (APA).
•
Metal SkinBottom: Bottom surfaces of the floor, within24 inches of any exhaust component,
must beprotectedwithaminimum skinof aluminizedor galvanized steel.
•
MoldedExpandedPolystyrene (BeadBoard) Insulation: Consider thickness and theASTM
specifications for water absorption, flammability, and thermal conductivity in yourmaterial
selection.

Sirens, lights, or other accessoriesmust not be located in thegrillearea, or other cooling inlets,
forwardof the radiator or air cleaner inlets. Keep all items to the sideormountedout in front of
thegrilleand cooling inlets. Reference: BodyBuilder Layout Book

Anadditional Air Conditioning system requires engineering consideration for compressor package,
mountinganddrive system. Systemplumbing, air flow, electrical loads and systemparametersmust
bedocumented (Ref Appendix IV).

AM-E0401
Dynamic crash situationsmust be considered inpackaginga stabilizer (or anti-roll) bar system. Avoid
bolts, bar ends, or other unfriendly projections directed at the fuel tank or fuel system. Stabilizer bar
installations shouldalsobeevaluated for rideandhandlingperformance.
AM-E0402
Avoid static body leans greater than3/4 inch. This is the side-to-sidedifferencebetween theheights
of thebody sidewheel houseopenings. Spacers between the springs andaxles canbeadded to
helpbalanceany lean. The total spacer thickness shouldnot exceed3/8 inchandmust not adversely
affect drivelineoperatingangles. Usinga tapered spacermay help control drivelineangles. Thebody
builder is encouraged toavoidasmuch side-to-sideweight imbalanceas possibleby balancing floor
plans in theoriginal body design, withdue consideration for the customer’s plans for equipment
placement.
AM-E0403
Rubber jouncebumpers are required in combinationwithadedicatedmetal jounce stop. Axles should
contact the rubber before themetal stop.
