Correct. The same size bags front & rear are not so much an issue. The installed height in the rear (bracket + bag) vs. what you're targeting for 'ride height' drop amount will possibly be the issue.

Those bags look like the standard C10 fronts (2600's/SS7's/Firestone 224c F6873) have about a 6" recommended ride height @ pressure. If/when you deviate from that recommended pressure, it impacts ride quality.

I ran that same size bag in the rear w/no bracket & it took only ~25psi to achieve my desired ride height (top of axle tube @ bottom of frame rail lip/approx. 2.5" from bottoming out on the c-notch). Now, I also had lowering blocks in the rear which should be a wash for your bag bracket since they prob both were similar in height. Below 30psi the ride was too bouncy & felt like it was basically too much for the shock.

You might want to set it up & verify dimensions. The smaller Dbl. Convoluted bag (2500/SS6's/255c F6781) are ~5" @ recommended ride height @ pressure (40-50psi likely). You get a much better ride quality w/the correct air pressure.

Food for thought. You sound like you weren't planning to go as low as mine was so you might be ok. I figure it's worth mentioning while you're still in the build stages.

A pic for reference . This was a bolt-in C-notched frame, bags directly bolted to the frame/Truck-Arm, & 1.5" blocks. I know it's a different year/body style but the chassis' are almost identical for the ride height concerns/comparisons....
