? for those running a factory a.c. set-up on there BB

Hey all
A buddy of mine called me yesterday wondering if I knew anyone with a factory air cond. set-up on there `73 big block. I told him I would see if I could find the answer to his question and this is the fiirst place I thought to come. Sounds like he is trying to reinstall a long absent factory a.c. system and is missing one of the steel tube spacers that goes over the long bolt that goes into the head. He explained that there are more then one of these because of the extra a.c. brackets. He needs the length of the spacer that goes between the head and the bracket.
Any help would be greatly appreciated.:thumbsup:
