I have a 1950 Chevy 3/4 and need the tire carrier for under the bed. The only part I see remaining is a track under the bed that is about 3 feet long and is right behind the differential.
I've looked in the assembly manual and can't find this track. Is this track part of the tire carrier?

I have an opportunity to purchase a 1953 3/4 GMC tire carrier. Will this fit? Is it the right one?
