This is an FYI or a psa about ujoints on my 89 b2200.
Thanks for posting this, I learned this many years ago since my truck had the supercharged 5.0 in it
Did you take measurements and find one that fit or do they sell this as a replacement?
Direct replacement.
And its in and fitz. Havent taken a testdrive yet but it fit perfectly.
If you go to the right place and ask, they will sell it to you - if you ask and they say something like "those are non-replaceable" then you are in the wrong place...
Done....90% of the vibration gone. And the test for the valve seals will be in the morning when i fire it up after sitting all night.
Still got some odds and ends left but most of them can wait.
