350B Torsional Isolator

[VT350C]

Hello all. So I am checking and fixing my torsional isolator for my 350C dozer (the one with 5 springs). It doesn't seem possible to find a flywheel from a 350D to convert to the rubber variant. So I will refurbish my 5 spring variant. Some questions. Below are pictures of my spider gear (name?) that fits inside the isolator splines. Wondering what you folks think about the condition of the splines. I am hoping I can reuse of course. Also posted is a picture of the old spring and new spring from John Deere. I believe the new spring is an accurate picture but it looks very different. For one both ends are bent to the same direction vs the old ones which have the ends bending in different directions. Was this to improve installation and wear?

You can see that it can wiggle very little.

I will take more pics of the isolator side of things, but I've been told if there is visible wear to replace springs, anchors, etc. I still have some facing on the back of the plate which is good, but will post to get folks opinions.

Thanks in advance for your help!
