I think they fixed early rocker length?? but I ordered mine a while ago and like many they sat for 1-2 yrs then found out during recent fit up they were off. I’ve got 34.63” width and panel is 34.13”. The body was so shot I cant trust any dimensions. I also ordered supports, they seem correct.
I too used a lot from Real Steal. Some good, some not so much. Avoid pass side floor pan, also both rockers are short about 1/2” so lotsa head scratching to come up with fitment plan. Still, it beats the thin pitted metal left yet. Did CCOT for gas tank as well. Some BTB for frame repair...
