Volvo: air conditioner mounting bracket, e mail address, mounting bracket

Question
I have a 1989 Volvo 740GL that is missing the tensioner on the compressor bracket.  Can you give me a description of it, maybe a blow up of the compressor area of the engine so I know what to go find?

Answer
Perry,
With the use of this site as the place where I answer questions, I do not have the ability to copy and paste a photo. If you send me a valid e-mail address I should then be able to send a photo.
It looks like a sliding bracket that has a long (100mm) by 6mm adjusting screw that goes into a locking jamb bolt to allow it to be adjusted using the 6mm long bolt and when the belt is tensioned lock it with the jamb bolt....
