Roy, I hate to continue on this because you have Hijacked the thread. This is not kosher because it starts two different streams of conversation. Cross talk, confusion and distracts from the original posters question. Please start your own post.
Steele is top of the line. You may have ordered wrong or they delivered wrong. However I see something weird on their site. You can order the run channel in "bulk" and it is said to be for sides and top. A person could interpret that to mean both sides and top. Which wold include division bar? It says order the 6' if using without vent window, Don't know what that means. Anyway it is .625 wide.
Their actual division bar run channel is .437 wide. That is a big difference. I don't have an AD truck so this may make sense. Or not. Don't know, just FYI. You mention 32" so that means you did order the division bar run channel and I guess you also ordered the bulk run channel.
Why are you focusing on Steele if you purchased from 4 different vendors? If you purchased run channel from 4 different vendors and none works, you have something bad wrong. 1/4 glass is OK. So that leaves a bend or wrong division bar..or you didn't remove the old one completely and left the old metal in there.
See you on the flip side.
