240z Diff Crossmember Exhaust Mount

Are there solutions for replacing the metal exhaust mounting bracket attached to the diff cross member (C in the diagram)? I'd love to find an original part, but that has been challenging.

Sadly the vulcanized rubber damper separates over time. I have a few old ones I resurrected by bolting in a rubber damper like the one below. It replaces the square rubber one between the metal plates.

Your picture helps 100%. I am missing the piece that bolts into the diff cross member. If I can't find one to purchase, I could fabricate a decent one using an angle iron.

Happy to help, should be easy to make fabricate one up. Let me know if you need dimensions, I can measure up one of mine.

I'd like to have the dimensions.  I had a NOS one until I sold it a few years ago.  Now, I need to fab one.  What part number did you use for the round rubber replacements?  McMaster Carr?

11.3cm L x 3.1cm H x 3.4cm W 3mm thick metal. Use these anti vibration mounts which can be cut down to a square shape. https://www.amazon.com/EASYEAH-Mechanical-Silent-Blocks-Compressors-M10x28-40x30mm/dp/B0D5JKBT44

I use a m10 thread PEM stud cut down to fix the damper to the bracket. https://www.pemnet.com/products/product-finder/hfh-m10-15zc/
