The correct color from the Willys Factory for your 54 M38A1 is 2430 OD. This is no longer produced by anyone. The closest ready made paint is Gillepie's 23070 or AJP's Late WWII OD.

In 1955 the Army switched to a third version of 24087 which is much more browner than 2430 or the second version of 24087. So most MV's when repainted in the field from then on were painted the new 24087.

2430 is on the left. 2nd version of 24087 is on the right.
The rod that runs down the center of your steering mast is the horn switch actuator. All those parts are shown in great detail in the M38A1 parts manual ORD 9 SNL G-758 and the TM 9-8015-2. If you would rather buy a rebuilt unit just call John at

The correct Carter YS950S carb can be obtained from Midwest Military
http://www.midwestmil.com/
This Carb is simple to rebuild and most problems passed around the locker room are caused by inadequate cleaning, old composition rubber parts in NOS kits, wrong metering rod, wrong springs, lack of use of proper technical pubs, and just plain ignorance.
Good luck on your resto and keep us up to date on your progress.
