I'm looking to clock the dana 300 in my CJ. I purchased a clocking ring several years ago, still sitting on the shelf.

Clocking ring will be going between a TF999 and a Dana 300

I haven't been able to get a clear answer in regards to the following-
Question is: Do I need the speedy sleeve spacer or not?

Thanks

John

i would also like to now this as i am planning on clocking my 300 with a 999 tranny

Yes you need a speedi sleeve or a longer input shaft.

anyone got a pic of how it (the speedy sleeve) is installed?
