Yep. I totally agree they should have known better than to give us hoses that were too thick for the length of the stock banjo bolt. Calling them and complaining is about as useful as..(put your joke here).
The problem Fred is that as amateurs we just don't know better yet as far as who to go to for that sort of complete upgrade. Brothers uses them and other than that one SNAFU, the system works. I remember being very irritated at the time and of course CPP is to blame. But the metric thing was GM's issue. In that same year they discovered their mistake and went to 7/16. I was very lucky finding only ONE supplier that made longer bolts in metric. 7/16 you can get all day in any length you want.
The REAL problem with the kit was twofold:
1) They use metric or standard and you never know which one you are gonna get, SO, if you do order from them, insist on 7/16. One part number shares both sizes.
2) The Banjo Bolt is not the problem. The aftermarket hoses have those banjo ends and they are too thick for the stock bolt.
And also, the jury is still out on that upgrade not beating your paint to death with there being no spring stop to keep the assembly from hammering your cab's toeboard. (AD years)
Once I get closer to the final assembly, I plan on looking that issue over and maybe making a bump stop bracket that ALSO should have come with the kit!
