I had to remove the original breather that Strange installed on my new 9" because it was in the area that I had to weld on tabs for an upper arm. I will be drilling and tapping a new hole in the axle tube and need some ideal on what to use for the axle fitting, catch can, etc. I have cage tubing in the trunk area that the can could be mounted to and some lift over 6AN PTFE hose that I could use if needed. Any ideas?
AME makes a nice compact unit. The key is to mount it high so not much fluid fills the can. OTOH you could look at a Morso unit which holds more volume.
If you have IDIOTS (Steve's Auto Restoration in Portland Oregon) put your rear end in -- and they choose to install a vent on the gear side of the ring gear - it will throw lube up at the vent and no matter what you do it will push gear lube out the vent....
LOL
Finch makes great stuff -- but like most things it also depends on the installation.
I will be removing my Strange 9" after mock up to finish welding on suspension tabs and get it painted. I am thinking about drilling a hole and welding in a bung on the upper front drivers side of the center section to run a line to a breather/catch can in the trunk. I think I read somewhere that this is where GMR recommends the vent.
