B-model Contour Cab

8 posts in this topic

If you are a big guy - get in the truck.

You will know immediately!!

Seriously, the concave cab was built to allow a longer trailer

to legally be pulled in the Eastern states, where length laws

were more restrictive than Western states.

The concave back panel is very obvious by its' curvature that

extends into the cab area, and therefore makes the cab interior

a little smaller. (about 6 or 8 inches smaller)

The concave panel was available as an option on most B models,

but was most common on the B-67 and the other shorter length

tractors.

A quick look will readily reveal a straight back panel vs. the concave panel.

Hope this helps.

I was looking at B67 pictures trying to see the difference in my B20's cab and could not tell much from the photos, most photos of them are from the front. I'm 6ft. / 240 lbs. and the B20 cab is kinda cozy. Is the difference in the curvature of the sides where it makes the transition to the back of the cab?

Take a look at this picture. The green one has the contour cab and the blue one has the regular cab

I see said the blind man, a picture is truly worth a thousand words. I appreciate everyones help.

I'm getting ready to order a complete glass kit for my 1953 standard cab B20 from this place.

Is the standard cab designated a CA30 model?

Pretty interesting picture -

I don't think I have ever looked at both cab backs

in the same photo before.

Everyone else might already know this, but I never realized that

the window in the concave panel is actually mounted

higher in the cab than the flat back window. (Look at the

body lines and seam roll between the roof panel and the cab corner,

and compare the two trucks.)

Thanks for posting the picture.

I've driven both and the concave back cab is easier to see out of to the rear for me. This is because of the elevation of the glass as you mention. I have to "duck" a little bit to comfortably view out the rear window of a standard cab. The one I drove was a B65 with a wrecker bed installed. You had to keep a eye on the winch drum to ensure proper spooling of the cable until tension took over.
