TR6 Steering Flexible Coupling

[Jim Hardesty <jhardest@infinet.com>]

I'm try to replace my flexible coupling. The old one was split, cracking
and would likely have caused a very scarey loss of steering in the near
future.

TRF only lists one part number, 150696 which is what I have here. 
Unfortunately, it doesn't quite seem to fit.  It is about 1/4 inch too
big diagonally (between the bolt holes).  I can almost get it to fit if
I compress the rubber coupling.  Is this normal?  Is there a good
technique for getting this done?  

Thanks for any help,
