Differences between 58 1/2 and 3/4t frames

Besides the front and rear axles and heavier steel, what are the main differences between the two frames. Main reason I am asking is I am looking at purchasing a long bed and want to make sure it will bolt to my truck

The link in my signature to the spec page will drop you on the frame page, has the dimensions differences. Basically heavier metal and deeper frame section.

Re: Differences between 58 1/2 and 3/4t frames

the factory assembly manual lists the 3200 (1/2t lwb) and the 3600 (3/4t) frame as the same frame
same dimension for every hole, see page: section 2, sheet 25.00
orrieg's link indicates the 3600 frame is .09'' deeper and .05'' thicker than the 3200 frame

the 3204 bed and the 3604 are also the same (sect.1, sht. 131.00), the 3804 bed is longer
