71 demon master cylinder

So I went back to the parts store again today and told them to look up a master cylinder for a 73 dart 340 with power disk brakes !! turns out its a different part number :banghead: picture on website shows master cylinder with the large resevoir :cheers: so that tells me that the part supplier numbers are all screwed up as stated, cause this is the same master cylinder that came with the demon in the first place ! lol so master cylinder is four days away :wack:

thanks again for all that helped in this mater Mike
