Thank you for all the replies.

BDW did you have to use any of the original AC brackets to work with the Vintage Air bracket?
Did you purchase the whole kit for Challenger from them, or did you mix and match?
If it is not too much trouble, can you please post or IM photos of the whole setup?

I plan to document my conversion in detail for other 71 to 74 B bodies owners so information and tips is very much appreciated.

I also plan on converting my 70 Challenger 383 to the Sanden setup.

Great forum. Thank you for the help.
