Has anyone changed out this

For this

And what type of modification does it take to make it work?
Alot you have to redo the frame and you will need a 91 92 airbox and the air to carb boot
I don't know what shock is in that red end on the earlier machine but its not stock or rite.
Lol
Ya I pulled the stock shock off so I could send it off to get rebuilt, it's a Warrior front shock. I know it's not right but it holds it up for the time being.
So if I understand correctly I will have to make the upper yolk/ shock mount and is there a lower shock linkage mount also that needs fab'd up?
Is there another option for me? My swing arm has a bunch of spider cracks. Or was this shock setup terrible to begin with? This is the first one I have ever owned.
There's noting wrong with that rear end setup. The problem is is its setup for a 120 lb rider spring and valving.
