"De-Smogged" timing belt cover bracket.

[squealingtires]

In the process of looking for a timing belt cover to properly spark time my '74 1800 spider, I was also searching for the upper bracket that both holds the cover and has cam timing pointers. In my search for the bracket I found this one on at an Ohio parts dealer. (I hope its okay to post a link)

I'm wondering if this is the right bracket for my application. It says its for "de-smogged" vehicles. My 1800 engine has an empty air-pump bracket and the additional belt area on the exhaust cam gear so I'm assuming this means its's been "de-smogged". What exactly is the is the difference between this bracket and a standard one? Currently I have the cam gears aligned with the little pointers that stick up on cam housings.

besides having pointers for cam gear timing, that bracket mounts the timing cover. If you still have the double exhaust cam gear it won't fit

Thank you @Mark Allison. This brings up another question. Do the pointers on the "de-smogged" bracket reference the same positions as those pointers on the cam housing? seems like a dumb question but I dont want to overlook the obvious.

yes, the front and rear pointers are in the same positions
