Another big task to undertake was the inventory of all the parts that came with the Jeep.
Bracket top left is the correct horn bracket - attached to LHS of firewall (LHS defined by sitting looking forward in driver's seat)
next two brackets along secure the sidestraps - attached with special shouldered bolts that are also used to secure the P-brackets (the forward mounts for canvas top frame)
eye bolt (look for the F-stamp) is one of two for side strap hooks - fitted to either side dashboard/front of door cutout - orientated horizontally for Fords and vertically for Willys
bracket to left of eyebolt is a petrol tank hold-down strap
rod bracket to right of eyebolt is for the axe handle - fitted on LH body side at an angle - forward of door cutout
the contact and wire looks to be a replacement horn wire - threaded down the steering column , out through a hole and then soldered to the contact ring - the outer tube has a spring contact plate
Those wheel rims are either MA/early slat grill MB or more likely later Hotchkiss/WOF single piece rims - most wartime jeeps had two piece split rims - good reproductions are available.
There are easy to follow, illustrated, instructions on how to rebuild the engine, gearbox and transfer case by the late John barton on the G503.com technical forum. well worth printing off a copy to have to hand.
