Canon FD 50mm 1.18 S.C reassembly inquiry

msteen1314

I'm in need of the experts out there in order to reassemble a fairly useful 50mm fd 1.18 s.c. lens.(Chrome breech lock)
The project was started while reviewing another video on a similar non s.c 50mm lens.

The video shows a pretty easy 3 step approach that gets you to the aperture blades which comes out for cleaning as a complete assembly. To my disappointment this is not the case with the sc variant.

Can the blades be reassembled from the front, seems difficult, but there may be a trick that you seasoned veterans are aware of. If not, is rear access the way to go and if so, any things to be aware of.

Any help would be appreciated.
