Is Bentley the way to go as far as a repair manual for my 83 urq? From what I've heard, the manual for that model year does not contain any information specific to the urq. Please advise. TIA.

..."Introdutory Servive Training Manual" on line sometimes. There have been a few on e-bay recently. The cover everything that the "red" book doesn't.

They have a good price on a new manual.
You might find a used one cheaper, but for a new one, their price is hard to beat.
