Breather Hose, Pinion Seals

Alright guys I'm struggling to find the right stuff I need for my 1971 jeep cj5 225 dauntless v6. Rockauto has had almost everything I've needed so far but some of this specific stuff I can't find. I'm not one to ask for help to stuff online so this is a first for me. Also not used to working on a vehicle over twice my age... I've searched the forums for a little too long and would really really appreciate some help!
Can't find the breather hose anywhere... Mine doesn't use a separate grommet or fitting, just fits into valve cover and over the fitting on the air cleaner. I think it was converted away from oil bath? It has a spacer underneath the carb. I need a new hose!
Also I had the dana 27 and pretty sure Dana 44 rear end. I need the front axle and rear axle pinion seals. I see the omix-ada ones that match up with my model year but they're cheapie seals and not sure I wanna run cheap on this thing unless they're known to be pretty good. What seals do you guys run?

Also, what is this thing I'm pointing to in this pic? Do I need it? One line I assume is a vacuum line of some sort?
Thank you!!

Glad you asked about that breather hose, maybe by chance someone will know where to get one, but I highly doubt it, has that special grommet. I went to local auto parts and picked both grommet and hose off shelf (NAPA). If your grommet is not too brittle, might just get hose and a coupler and splice in.

I’ve attached drawing for temp sensor connections.

I have used a bunch of the Omix pinion seals without an issue. Best to polish up the seal surface on the yoke to make sure that a groove isn't worn into the yoke causing a leak no matter how good the seal quality is.

 

Thank you! Mine doesn't have a grommet actually, the hose is all one piece but the hose is good. So I'll just find a grommet and fitting and be good.
That number 4 sensor.. Do I need it if I deleted the heat riser?

 

No, you don’t need it if hot air door deleted. That sensor is normally connected to vacuum port toward back of intake manifold, make sure it’s plugged so you don’t have vacuum leak.
