Yeah, was a pain in the a$$.
When I did my 360 it was nice and easy, of course it was upside down on an engine stand. This one was still in the 90 Grand Waggoneer (couch on wheels 😉).
I have searched online and haven't found anything. But if I did, I know I'd buy some for myself, and I know others that would as well.
We actually looked into a nitrile piece but they wanted a 50K start up and stock fee.
That is crazy expensive!
Figure there has to be enough of us AMc V8'ers out there to make some demand for it. 😉
