Would these work on a 71 Challenger?

I always thought that a Challenger uses a 9" booster but SSBC has a 7" booster listed for it  http://www.ssbrakes.com/products/detail/303/?make=Dodge&model=Challenger&year=1971  or a 9" listed for it  http://www.ssbrakes.com/products/detail/301/?make=Dodge&model=Challenger&year=1971  . Would either one work on it or a 8" booster as well? Thanks

These are their add on power boosters, "for OE non-power disc brake cars. Will not fit OE power brake cars" not replacements.
Here is a source for new OE style  http://www.piratejack.net/brakebooster.html

I did see those from Piratejack's but they do not have the 9' in either chrome or stainless but I was wondering if  the 8" booster would work?

As far a the SSBC piece I suppose this is setup to be a direct bolt on to a manual brake car so if you have a manual brake car you will be OK if you have a power brake car then you may need the manual master cylinder bracket & rod. You should contact SSBC to see what they require.
The pic of the Chrome from piratejack is not of a unit they recomend for Mopars, notice the much larger bolt pattern.

Don't mean to hi-jack this thread, but what boosters did mopar use on 73-74 E-bodies?  I have a 73 Cuda with factory Disk Brakes and I need a booster.

in '73 they changed to a slightly flatter looking booster that is maybe a little larger in diameter than the earlyer models. Here is a pic from NAPA of a rebuilt, it originaly had a gold irridate finish
