Thanks exekiel69 for the pic of your new clutch clearly showing the cast style of pressure plate body. I thought about going with the 13" but some of the ads (on Ebay anyway) led me to believe I would need to machine my flywheel or purchase a new one for the large clutch on my Getrag flywheel. Did you have to mod/replace your flywheel for this Sach's unit?

 

I believe it is the larger hub upgrade that needs the flywheel machined not the actual clutch diameter itself.

 

I have the factory flywheel, I had it turned for the new clutch and machined for the new pilot bearing (got it from quad4x4), here is a picture of it.

After the rebuild I notice more noise, it goes away when I press the clutch pedal thus releasing the clutch and putting pressure on the TO bearing. Transmission shifts better than it ever did before, I really like it, not sure about this noise yet as the retainer is new and the pre-load was set by Me down to zero, no play on the input.
