those images are for the early 944 with steel trailing arms,
the later 944 with alloy arms are the same as the 968, they can be replaced but your only choice is FlowFlex, PowerFlex, and you have to leave behind the steel shell of the old bush, the alloy is too soft for just the bush alone, I would be surprised if they are worn out
I can tell you Part 2 in the 968 image is an absolute horror to replace, my buddy snapped his spring plate flange trying to get the new one in, Items 4 and 11 the mounts come to close on $1000, and the spring plates (item 23) the rubber bushes have to be cut / burnt off to replace with powerflex silicone or elephant racing solid, but I would not use solid unless its a track car,
you can buy remade ones
