Its this type of info I`m looking for. What is the difference between Cougar v.s Mustang hangers? Upper or lower part? Both?
Thanks

John,
If you need some good hangers for a Division 2 car or driver, the current reproductions are pretty good and will work just fine for you. However, if you're looking to establish and document all the differences between "similar" hangers, it's involved. Mustang and Cougar are different. The hole spacing is different on Cougar for the muffler hangers, and the upper hanger part is different too. Rear frame hangers are mirror images for Cougar and are not for Mustang. 1970 Mustang uses one DO number and one C8 number because it is common to single exhaust Mustang (rear hanger). Additionally, single exhaust muffler hangers for Mustang appear the same as 1970 hangers (for one side only), but are not, the hole spacing is different for those too (there are three different hole spacings for different variants). And 1970 and 1971 muffler hangers are very slightly different, but would probably work on either year because they are so close to being the same. If you have some photos of ones that you are trying to identify, post them here and I can tell you what they are for. NOS ones are sometimes available but could cost you $600 - $1,000 for a car set. Used ones are typically pretty pitted from rust since they were bare steel. If you just need some good 1970 dual-exhaust hangers, buy the reproductions, they are pretty good, especially for the money.
And to answer your question above, all 1970 dual exhaust Mustangs used the same hangers. So Boss 429, Boss 302, all Mach, CJ/SCJ cars all the same hangers.
