Steve Beckman,

I have redrawn my manifold bracket to accept the flanged type header
tube. The four holes are to accept the top clamp plate. I have made the
plate a little bigger to accommodate this - now if I can only work out
the best way to do the flanges, but I'm working on it.

George.

why do you want to retain the two original exhaust flange bolts? I think
they are over kill.

I have been using the four bolts only on my 12A based one rotor from day one
on, and never had a problem. I also use the upper original bolt on the PP
intake manifold.

Richard,
There is a benefit for those for those not wanting to drill tap and stud the
Al housing and having a direct bolt on arrangement. The studs would come out
of the bottom flange as shown in the drawing - just another option!
I actually included the drawing for those wanting an accurate flange
drawing. I had difficulty getting it that accurate, my first flange was
about (.75mm) out, luckily I had left enough play in the mounting holes,
that's why their 11.5mm.
