Here's how you fix the vacuum issues with the CAD once and for all.

On my '84, I just slid the collar over and used a stainless steel hoseclamp to keep it in place.
Figure that in 90/91? They removed the axle disconnect anyways.
I still see my busted fork in the garage once in a while.

AT LAST !!!! The diagram I've been looking for since I bought the beast!
Thank you, thank you, THANK YOU!!!
Now, if someone can tell me where the red line hooks up to the manifold vacuum. Mine is just laying there next to the distributor, and I have no idea where I should connect it.
Can anybody give me a hand?
