Just picked this up

Here is the 727 and 440 that came with it.

I did not realize it but the yolk pulls right out. I think it was left in there so the trans would not leak.
This was why I was confused because I thought I was buying a proper car long tailshaft 727 and I didnt think they came with a fixed yolk on them. only the short motorhome ones did.

This unit it supposed to be a runner though its been sitting for 6 years in dry storage.

I plan to flush it a couple times once she's in. Any other suggestions??
