Need a ZXR750 subframe

This is a copy of my ad in the "parts wanted" section:

I'm looking for an L model ZXR750 riders seat subframe; anyone got one lying around spare thy don't need?

Doesn't have to be pretty as it'll be getting hacked up then powder coated but needs to be straight.

Happy to pay postage and a reasonable price for the part.

If there's a spare riders seat to go with it I'm happy to pay for that too!

I have a spare ZX9R subframe to suit a B1. Guessing B2 and B3 would be the same.
Can you use it ?

No mate, sorry.
I'm after a ZXR750 subframe, completely different bike.
I think I may be sorted now anyway.

I know they're different bikes. I assumed when you said "hacked up" that you were going to be modifying it somehow.
No probs. All good mate.

I am but I need the mounting points to be the same
