GM Field Remedy on these
The old style that push through the shoe and twist into the back plate have been superseeded to the later style that has the pin coming through the back plate and then uses the retaining cups that twist onto the pins.
The offical way of doing thses is to remove the rear hubs so factor in bearings while you at it, there are a couple of ways of removing the hubs, first is to pay a garage for the grief or find someone who is able to help as its the removal of the arm and the use of various hammers.
You might find that if you can undo the bolts that hold the back plate in place and the hole isn't to damaged you may be able to feed the pins in from behind but be warned if you strip the splines on the bolt head you will have a hell of a job to get them out
If you need to replace the back plates then other people have done this by cutting the plates in half and then fitting which avoids the need to remove the hubs. This isn't an offical GM way of doing the job and you have to be careful how you cut the plates so more research would be needed
