I am aware that the truck does not have body mount brackets but don't know if the rest of the frame is the same as a car frame.

Thank you for your help!
You will need to add the four body mounts (two each side) to the side rails of the pickup truck frame. You will also need to add the two cowl braces (one each side) as well. The braces are bolted in and were there to offer more support at the cowl section for the more flexible convertible body.
The convertible frame does not look identical to the truck frame but if I am reading your post "between the lines" it doesn't appear that you care.
Other than the aforementioned differences, the frame will be a clean swap.

By the way, like you, I have read claims that all '35 - '40 frames are identical. Each time I read this I am left to wonder who made this poop up? Probably the same folks that believe in "alternative facts" continue to claim all these frames are identical. They are not. Most noticeably are the front cross members between the years and even at times, the models within the same year.
There are also NUMEROUS subtle differences between years that while perhaps arguably minute, make a difference to a serious restorer.
