Getting ready to finish up the 14bff drum-disc connection. I have ORD's axle lines and a new oem rear line that drops down from the bed to the pumpkin. Wondering what if anything I do to seal the threads at the T between the single rear line and the two axle lines? Do I use silicone tape? The yellow stuff for gas lines? I hate overuse of RTV but maybe? Just thread them together dry and tighten em down good? Thanks guys for all the help getting this far.
