Tool to stretch spring

Boy if you could get the nut loose and the main bearing arm loose. Then everything would side out a little and maybe just enough to hook the spring.
I'd try this with a rope first, and if that doesn't work then make the T-handled exhaust tool (with hook).

Any chance you can loosen the disc shaft and partial slide it out. Then you'd be working with slack springs.
As already mentioned!

Expand the spring and insert a tool to hold the spring in it's expanded form, install the spring and then knock the tool out.
The tool is simply a length of tubing (ID of tubing - OD of spring) cut in half length ways with a large washer welded on each end. A large piece of angle iron will also work in lieu of tubing.

Look at the spring-holding as it passes through the round tubing to which it is mounted.
It appears from the photo that the spring-holding shaft is secured by a roll pin or bolt through the spring-holding shaft after it passes through the tubing.
If that is the case then you can remove the pin or bolt, take the shaft out, attach the spring and then insert the spring-holding shaft back through the tubing and replace the pin or bolt.
You still may have to use a lever to pry the mechanism back thus stretching the spring in order to re-insert the shaft through the tubing. But this is much easier to do than just pulling on such a stiff spring and you have multiple options on how to do this last operation. Hope that works for you.

This is exactly how we use to change them back in the day. Once the spring is attached and you have the leverage of the scraper arm, with a little finessing it's easily replaced. (drive the roll pins out with a roll pin punch)
Good luck, watch those fingers!
You don't have to stretch the whole spring, only most of it. Insert a piece of suitable flat stock between the coils near the end and pull it. Put a hole in one end of the flat stock firts. Then a come-along can get into position while you turn and twist the spring end. I use loops of plastic bale twine. The twine melts a bit as you pull it around the spring end and keeps the tension fixed while you jocky the spring end around.
