Your money, effort, and time are much better spent doing the cross and roller conversion. If you're bound and determined to keep the ball and trunnion setup, you might call Andy Bernbaum about that breather.

I know I'm right....
interested in WTH "polished Jute" was...now I know its just a thick piece of felt strapped between the boot and the shaft..Then I read this...
"I fitted a Burnbaum's Boot and it just fell apart, after maybe 100 miles. I when to a Universal, CV Joint place (front wheel drive shaft ) and they had one in stock rubber was a better quality with better clamps for $ 7 still intack after 12 months..." Viewing a thread - BUYER BEWARE-Burnbaum's U-joint boots
So it looks like someone didnt like that part. But if its the only game in town, you may still wanna play.

I opened the boot to re-grease on a larger ball & trunnion from a B-body (64 Belvedere) and didn't notice any jute for "breathing". I also have several A-body rebuild kits (not for sale) and they don't have any jute type thing.
The ball & trunion is a fine design and rugged, just hard to source parts. You can find them occasionally if you search. I posted all PN's several times. Re changing to the slider design which Dan linked, some Jeeps (67-81 std shift) used the B&T and many do that mod. There is an ebay listing for a Jeep drive-axle for $150 in any length, but don't know if it applies to that mod. Someone might inquire and let us know. Also, if junkyard picking, 64-70 Dodge A100 trucks and A108 Vans used the same B&T PN and they probably have a longer driveshaft (usually easy to shorten).

Thanks for posting the FSM drawing. I'll look for that tiny "breather" in the rebuild kits. Apparently, its purpose is to allow air to flow out as the driveshaft moves forward (rear sinks down), so the rubber bellows doesn't bulge (and reverse when the rear lifts). CV joints are similar, but I never noticed a breather in them. Instead the rubber bellows just clamps tightly to the shaft on each end.
Makes one wonder if the breather is necessary or even desirable. Seems like if you install the driveshaft and get it at nominal length, then clamp down the bellows, there wouldn't be a permanent bulge and the bellows could accommodate slight changes from rear-end bouncing. Wouldn't apply to those who drive long periods off-nominal height, like mafia guys carrying bodies in the trunk, but they prefer large vehicles.
BTW, if one needs to replace just a torn rubber bellows, without removing the driveshaft, people say a split bellows repair kit for an old VW Beetle driveshaft works.

I took 3 apart and none of them had it but the boot was busted on all of them ,Maybe they fall out when that happens......
