Is there a right or left correct placement, or can it be placed either way?

Willys Jeep Parts Tech:
I do believe it can go either way.

I like the color of the Jeep on the cover of the 2017 calendar, Is that color in the Jeep color charts ?

Willys Jeep Parts Tech:
Sorry, you would have to have a similar color matched there locally at your paint shop.

I have a 1949 Willy's Jeepster with a Dana 23 rear end. I did not have the differential spider gear spacer in the axle and need to replace it. Do you know if this spacer would work for the Dana 23 axle, or what the dimensions of this spacer are?

Willys Jeep Parts Tech:
926544 is what you need there.
