I think you’re right in that the diagram in your Parts Catalogue is much better than the one in my July 73 version. Much better appreciation as to what bracket 150676 actually looks like all round now.
I agree that getting duplicate of your bracket will suffice for my need. I’ll pass these photos onto to my friend in engineering works and see if we can now reverse engineer the bracket of concern to me.
Many thanks again for helping me out. Much appreciated.
Cheers
David
