gimbal berring 4.3 sx-m drive

[Lawnpro979]

Ready to order parts. "Never replaced gimbal before" and I need u joints. " quite a noise coming from the lower unit"
I'm confused about the parts I need. I'm seeing a kit with bellows included. And I'm seeing gimbal alone for 40.00 to 90.00

I didn't find it here on iboats

And I'm not sure about any seals I'll need
Thanks in advance
