I managed to strip out a banjo bolt on the brake line at the top of the line to the rear master cylinder. (John Z -probably why I couldn't get any fluid out of the ABS on the back side.) This one is a royal "B" to get to anyway. I watched Kirk put a wrench on it to support it but mine had a bracket and a bunch of taped wires made it very difficult to get a support to it. I torqued to 18nm and stripped it out. I could not get it to stop leaking prior. After removing the rear shock I was able to remove the stripped one. At least I know I can do that when it is time to upgrade my rear suspension.) Here is the question. The BMW dealer wants $22 for a single bolt. Looking for some experienced opinions on weather to go with an aftermarket bolt of the same size off Amazon at 1/10th the cost. It will have a bolt head vs. the hex. Wondering what torque will be appropriate if I go this route. The downside I see is you can get a stripped hex bolt out with vise grips but I'll be drilling and tapping a bolt if I use my super human strength on it again.
