You guys are talking around and about three different boots. All of which have been linked above by me or another informed party.
1. Black accordion style boot with plastic rim that often breaks.
2. White (sometimes black) boot that is a sound and heat barrier that is molded to the outer accordion style boot from the factory. This boot often tears be because people get impatient with it.
3. Black small and taller and somewhat narrow accordion style boot that goes on the shift lever just under where the upper and lower shift lever are bolted together.

I do not remember the details from 2 years ago. But when I was looking at doing the bronze bushing, due to the fact the previous sb kevlar bushing held up like junk, I was happy to learn frkm sb that they use a much better setup on their dd clutch. Almost like they want their $1,200 clutch to last.

It is a good setup for heavy work with extra power. Though a good single disk is still a good product any less expensive.
180/30 and up and heavy towing often, I personally would go with dual disk.

I have MTL in mine also and have been very happy with it. Might buy a gallon of MT-90 and mix it with the two left over quarts of MTL I have next time. I'm a Schaeffer fan but they don't seem to have a product that fits the bill perfectly for manual transmissions and Redline is tried and true in that department.

Wow, a real pilot bearing! I'm impressed. If I knew at the time I'd gladly spend an extra $400 and got their dual unit, perhaps is wouldn't rattle my teeth every time I start off. Thanks for the pics.

Anyway, it is a bit of an in-between when looking at the MTL and regular ATF and my transmission is very happy with it. The same build component trucks are not the same after 20 years of being on the road. I am glad you found MTL to work for you, I wish I had known you ran MTL a year or so ago. I gave a full case of it away to someone on the OBS forum with a ZF5. He paid for shipping, but that is a fraction of what the MTL cost me.
Red Line make some nice products, they are pricey, but worth the cost based on my butt-dyno results.
00t444e, looking good and like you are progressing well. Thanks for posting the pictures for those interested to dissect.

I put the SB HD clutch in mine with an upgraded Fitzall bearing and input shaft shaft repair kit, it still rattles, not as bad but still rattles so I wouldn't put the blame on the bearing.
